I’ve a De’Longhi Microwave oven in my kitchen that I’ve had for years. It’s easy to use, fast, and most importantly to me it’s big enough to allow a big dish to fit inside, which comes in handy when reheating something like lasagne. The turntable (the bit that spins inside) has been a bit flaky for a while, and a few months back gave up the ghost completely and no longer rotates. The rest of the unit still works well but you just have to remember to keep stopping it and turning whatever is cooking to prevent cold spots.
Microwave ovens appear to be quite cheap – there are always offers in supermarkets, but generally those tend to be quite small. To buy a replacement that is on the larger side would be well over £100. So a quick google reveals that the turntable motor can be bought online from various stores for not much – 4ourhouse.co.uk has the correct part for only £8.99, so I thought it might be worth a go.
It’s at this point I probably should insert some sort of warning saying this is what worked for me, you should understand the risks of opening the casing of any electrical equipment, and that opening the case of a device that emits microwave radiation needs very careful thought and should only be carried out by a competent person.
I left the microwave unplugged for a while to ensure any capacitors were nicely discharged. I also removed the glass plate inside to avoid breaking it. Turning the microwave around revealed several warning messages including:
Do not remove any covers unless qualified to do so.
Hrm, was this a good idea? Turning the oven upside down revealed a single plate of metal at the bottom of the oven. To remove the bottom plate would involve removing a large number of screws around the edge of the frame, and heading towards the bits I probably shouldn’t touch. However, there was a punched metal section through which I could make out the turntable motor. There was also an odd message stamped alongside:
Caution: Remove sharp edges after cover removal
Looking carefully, I could see that part of the underside was only held on by a small number of thin metal strips that could easily be cut. The cover piece removed could then be rotated and would slot in two holes, requiring a single screw to hold the cover back on.
Checking I had a screw that fitted the hole, being careful of the depth, I carefully snipped away the metal to release the motor cover.
The warning message was correct – there were some very sharp edges on the areas that had just been snipped, so I trimmed them off. We’ve accessed the turntable motor, but without exposing ourselves to any other parts of the oven. The motor itself is very small, and is held in with a single screw. The small piece of plastic emerging from the motor goes straight through a small hole in the floor of the oven, and is straight onto the part that the glass plate sits on – no complicated gearing is involved:
After a few weeks of waiting for the part to come in stock, the replacement motor arrived. Swapping out the motor and prising off the spade connectors was quick now I knew how to get inside the housing, and a just a few moments later we were back in business with a rotating turntable.
