Question about GE Profile PEB1590 1.5 Cu. Ft., 1000W, Countertop Convection/Microwave Oven, Convection Cooking

Open Question

Not heating Relay-type click sound upon start, interior lights and timer counts down, but no fan and no heating in either microwave or convection mode. Door safety switches seem to be operating correctly (tested with door open in convection mode, got expected behaviors). Unit only ~18 months old, so a little early for magnetron to die, and since convection mode also not working, suspecting a relay or capacitor?

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

Hi there,

Microwave ovens use a series of micro switches to operate as interlocks to ensure the unit will only operate once the door is securely closed.

If these locks are not operating properly, the timer would count down just like it was operating. There will be no noise like the normal vibration or fan sounds when the start button was pressed. It will simply act like it will operate, but it will never turn on any of the components.

You would need to check these switches if they are functioning properly and would need the help of a qualified technician to test them. If you plan to do it yourself, Check if the switches are mechanically operating and that electrical continuity would change as it was actuated.

There will be at least three of these switches aligned so they close in a specific sequence when the oven door is closed.

This closure process is designed to prevent someone from just sticking something in to actuate the switch and run the microwave with the door wide open and becoming exposed to the microwave energy.

Two of the switches are in place to provide power to the units high voltage section and to tell the control board when the door has been closed. These are usually normally open switches.

The third switch is called the monitor and acts as a safety switch blowing the internal appliance fuse in the event any tampering is going on, and this one is usually a normally closed switch.

If you find the fuse inside your microwave is now an open circuit, check the monitor switch as it may be the cause.

Hope this helps.

SOURCE: GE Spacesaver Microwave not heating, inside fan not working

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

Light, fan and timer work but microwave does not

Microwaves are pretty much a non repair item. It will cost you more to fix than it would to replace.

Microwave won't heat food, new smart board unavailable?

GE Microwave Model # JE1860: Unit does not heat. The timer counts down, but the oven does not heat.

When you hit Start to cook, do the inside light, cooling fan, and turntable come on?

Any unusual noises? Is it louder or quieter than usual?

These answers will help me judge whether it's in the high voltage section (magnetron, transformer, or diode) or the control section (door switch or control board relay or connection).

Does microwave ovens make noise while it is in process of heating?

It seems like it is the first time you either own or using a microwave oven. Yes, there are more than one fan/motors inside a microwave, depending upon the model/type.
