A built in microwave will almost definitely cheaper to repair than to replace

We repair a great number of built in microwave ovens. For many years now new kitchens have had the option to have a microwave or combi oven fitted within the wall units to keep the worktop clear.

The microwave tends to be based around a free standing microwave so from our point of view will be just as easily repaired – once it is out of the unit. To that end if you can remove it from the housing why not bring it into our shop to save the call out. The repair will be even cheaper.

The unit often has the trim pieces top and bottom fitted to the oven. if you can see screws then they are probably just locating the oven within the housing. It is usually sat on a plynth to centralise it in the housing and more often than not held in mainly by gravity.

Like a lot of built in appliances, it will be a lot easier and no doubt cheaper to repair the microwave than to have to find a replacement that is the same design and size.

As you can see from the photos here of a typical example that has come in for repair. The trim is fitted to the oven so has come out of the housing with it and there are even hand holds for carrying the oven to your car.

If you are in our repair area please follow this link for opening hours and bring your microwave into us and we’ll see what we can do.

How to replace the waveguide cover in your microwave oven

If your microwave oven is sparking or ‘arcing’ during cooking it may be that the waveguide cover is damaged. Usually the cover is made of a material called mica. Although strong and tough when new, over a period of time this cover absorbs moisture and food debris and becomes soft or breaks. If moisture or food embedded in it starts burning it will go from bad to worse quite quickly and if not replaced can cause irreparable damage to the microwave. It is advisable to replace the cover as soon as possible to prevent damage.

Note: In the interest of safety, please make sure your appliance is unplugged from the mains and that the area you are working in is safe.

Before you start you will need to know your model number in order that you order a replacement cover. 

You can then either order the correct shape cover to fit by make and model :click here to look for parts by make and model

or you can order a piece of generic mica material and make one to fit (supplied with easy instructions) : click here to order waveguide cover material

What’s my model number?

This can be found by opening the door and viewing the information sticker located on the left hand side of the control panel. Alternatively your model number may be located on the back of the oven.

Removal process

Changing the Waveguide cover is an easy process.

  • Firstly, start off by removing the screws that hold the cover on.

(Some models may have a plastic rivet holding it in place, simply prise the rivet out)

  • Then, once you have removed the screws/rivets you can bend the sides of the cover in and pull off the original cover.

(You may notice the cover is greasy, dirty and maybe slightly burnt. The reason Waveguide covers get like this is they absorb fat splashes and general grease in the microwave)

  • Thirdly, clean up the area behind the Waveguide cover using a good microwave cleaner to ensure the surface is near spotless

Fitting your new Waveguide cover

  • Line up your new cover in the Microwave, ensuring the screw/rivet holes line up.

(If using rivets, place the bottom half of the rivet in before the Waveguide cover)

  • Fit the screws back into the new cover and tighten

(Push the top half of the rivet back into the Waveguide cover holes)

Please try to keep the Waveguide cover clean by wiping gently occasionally with a damp cloth after use.

Really low power microwaves

We have been asked occasionally to supply microwave ovens that output even less than the usual 500 watt microwaves that we already sell.

Just to confirm, a microwave oven draws nearly twice the power in watts that it produces in microwave energy (also watts). Unfortunately our 500 watt ovens need a little more than a 1000 watt generator will cope with – they draw about 1150 watts.

We have just listed on our website by special order a microwave that draws less than 1000 watts so it will run on a 1000 watt generator.

It outputs 320 watts microwave energy but importantly draws only 810 watts.

We have only a few of these so don’t keep them in stock but can make them to order usually within a few days.

Microwave Oven Power – Important Information for regular users

Following on from an earlier post, I wanted to let you know about the inherent problem with microwave power inconsistency.

Microwave ovens produce a set amount of power. This is normally indicated in the specifications such as ‘900 watts output’. However, as the components heat up through use the power level drops sometimes by only a small amount each time the oven is used.

The power drop off has always occurred but in earlier, older ovens the quality of the components used often made this drop off less noticeable. New ovens today tend to built of a lesser quality using more budget components so this effect is more noticeable and therefore more important. Independent tests carried out have found that in some instances microwaves may produce as much as 50% less power on just the second cook cycle.

It is extremely important if you use the microwave for regular repeated cook cycles ( such as heating more than 1 successive ready meal) that you check that the food is in fact piping hot not just that you have just done the same cook time as before and assuming that results will be the same. Because of this power drop off the cooking results are quite unlikely to be consistent.

24 volt truck microwave oven repairs

Just a reminder that our repair service for the 24 volt Samsung Roadmate microwave ovens is still very popular.

Samsung roadmate 24 volt truck microwave oven

Although parts are no longer available for these ovens, we are able to repair the Inverter circuit board which seems to harbour most of the faults. Just send your oven to us and we will diagnose the fault and let you know the cost to repair and return the oven to you.

We now have on offer an alternative oven in the form of our very own Drivemate 24 volt microwave oven, which although slightly larger offers many more benefits than the Roadmate it will replace.

Heating plates in the microwave

Just recently I have had a few phone calls from customers who have damaged their microwave by using it to warm plates.

In a nutshell, don’t use your microwave to warm plates.

Very briefly, microwave ovens work by emitting microwave energy into the oven. This in turn agitates water molecules in the food or drink in the oven. The friction of those molecules creates heat and – hey presto – hot food is the result.

Plates have very few if any water molecules in or on them, therefore if you only put plates in the oven, the microwaves will bounce around the oven looking for something to absorb them. Eventually, something else in the oven will get warm. it might be the plastic roller ring, the mica waveguide cover or any plastic parts of the inner door.

It may be that you have been doing this for a while with no problem, this could be due to a number of factors such as the quality or type of plate. Some cookware may have moisture inside which more readily absorbs the microwaves, whereas some cookware will be completely invisible to microwaves (this wont get warm at all).

On a few occasions problems have occurred where the microwave is a replacement microwave and is either much more powerful than the last or through its design is less tolerant of microwave energy bouncing around inside.

Either way, if the microwave is used for heating plates eventually some damage will occur. The plates could break. The microwave oven might even end up cooking itself ultimately which will of course result in costly repairs or replacement.

If you really want to use your microwave to heat plates try putting a bowl of water on top of the plates so that most of the energy will be absorbed or if your microwave is a combi oven warm the plates with the grill of convection instead. It may take 5 minutes instead of 1 minute but wont affect the microwave in any way.

Paint peeling off inside the microwave ?

The interiors of microwave ovens do tend to rust over a long period of time. This can be due to a number of reasons, the main cause is the generally thin coating of paint is damaged by the continuous rotation of the roller ring, antagonised by spillages or condensation and the warmth of the oven create perfect conditions for rust.  Rust is difficult to completely cure but certainly using our touch up kit and a little tender loving care can reverse the unsightly looks.

paint lifting from cavity

Please read through these instructions and follow them carefully. Perfect results are not guaranteed but if you follow them carefully you will reduce the poor finish caused by rust and wear.

Our microwave oven cavity paint touch up kit is available in different colours from our online shop – available online at kitchenwareonline.com

microwave paint

Microwave oven touch up paint kit

Allow a period of time when you are not going to need the microwave, the paint needs at least 6 hours to dry before the microwave can be used otherwise the paint itself will heat up and spoil.

Ideally unplug the microwave oven to prevent any accidents or risk of electrocution.

Remove the glass tray and roller ring.

Place some old newspaper in front of the microwave in case the paint drips.

Rub down the affected area firstly with some coarser glass paper sheet and then some smoother grade (supplied in the touch up kit), to remove any loose flakes of paint and as much rust as possible. The smoother the prepared area, the neater it will look when finished.

Wipe over the area and wipe out the oven cavity with a dry cloth to remove all dust, debris and moisture.

Shake the tin of paint vigorously for at least 30 seconds and then open it with a small screwdriver or knife and stir thoroughly with one of the stirrer sticks.

Using a paintbrush, carefully paint over the affected area. The paint does dry quite quickly. A better finish is achieved with several thin coatings of paint rather than applying a large amount of paint in one application. This also reduces the risk of unsightly blobs of paint.

Once complete, leave the microwave oven unplugged with the door open for 6 hours at least to allow the best opportunity for the paint to dry.

If the paint tin lid is pressed firmly back into place, it can be stored for many months. The stirrers supplied in the kit can be re used once dry. The brushes can be cleaned using turpentine or white spirit but we have supplied 2 in the kit with the view that it may be better to discard the used brush once used and then use the other if necessary at a later date.

Paint contains Cobaltcarboxylat and Butanonoxim and can cause allergic reaction. Full specification upon request.

Drivemate 24 Volt Microwave

The Drivemate has arrived.

After a gruelling 2 years product development we have taken delivery of the first batch of our new 24 volt microwave ovens.

We can now offer an in vehicle cooking solution for any 24 volt vehicle. The Drivemate is based around a 3000 watt pure sine wave inverter. It has the capability to ‘invert’ 24 volts to 240 volts mains to power the microwave oven as well as other small devices in the cab.drivemate-view-001

Connected via a 50 Amp Anderson connector to the battery feed to the cab, the unit has its own isolation (power) switch, 2 x USB charging ports for mobile phones and tablets and a specially designed display to report the battery power available. Specially designed (patent pending) circuitry also prevents operation of the unit if the voltage is too low that the vehicle might not start.

The Drivemate is available in 2 variations. Either as a complete unit attached to the 20 litre, 800 watt microwave/grill oven or as a stand alone power supply to power your own microwave oven with the option of mounting straps to secure it in a different cupboard or under shelf.
