I have a GE lvm1750dm1ww Thought I was using the timer but by mistake I used the time cook. The unit is dead now and the fuse is good. Any help????? Thanks, Ron

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

Magnetron and diode most likely. Need more info.

Good Morning,
Sounds like it is not heating up. First, check the unit for a blown fuse, if the fuse is good then the Magnatron tube is bad. Let me know if this helps and thank you for using FixYa!

Try to unplug your microwave then leave it for 1 hour the purpose is to reset and drain stored current after 1 hour plug it again ,if still notworking there something wrong inside. Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows,you need to replaced it or you need to have a qualified appliance repair technician replace it.

Hope it may help you;

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.

The pop was probably the high voltage rectifier diode blowing.

Also, what usually happens when a microwave is run empty is that the magnetron overheats and the thermostat opens and kills power to the unit until it cools back down, then the microwave comes back on in the off condition, ready for you to set the clock.

I would suspect you need to replace the diode and the thermostat, then once it powers up you can test to see if the magnetron still works.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

You can download GE owner's manuals and installation instructions here. Those are very handy if you have to remove it from the wall to replace the magnetron should it be bad, too.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Chances are it overheated the magnetron and then blew the thermostat on the magnetron.

Hopefully the thermostat did its job and protected the thermostat from damage.

A microwave can be dead for many reasons.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

Found this under GE instead of Maytag, but can answer for you here.

It may be the internal fuse, but more likely it is the thermostat on the magnetron.
