Question about GE JVM1540SMSS Microwave Oven

Open Question

I just purchased and installed my GE JVM1540SP1SS microwave and it's dead - not showing any power. I plugged back in the GE microwave that was replaced and it powers up fine. I've also plugged in other products in the power outlet and they all power up - just not the new microwave. Any thought as to why?

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

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

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall, in which case you can download GE owner's manuals and installation instructions here.

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 (or GFI) 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.

There should 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 by entering your full model number here. Once you have the part numbers, though, I would suggest ordering parts here at a much lower cost.

One of the most common problems with Ewave microwaves is a loose blade on the cooling fan, causing the magnetron to overheat.

At this time looks like the magnetron, the magnetron TCO and the fan blade have to be replaced.

SOURCE: GE Sensor Microwave JES1855 died

Mine went dead after about 6 months. I had problems with my breakers and I found out that it was the microwave that blew all of them. I also found out that this perticular microwave is a fire hazard and should be recalled. It has caused me alot of headache. The breakers in my house are brand new and they are put out by GE also. It caused me to loose the food in my freezer, I did not know my freezer had lost power. It would cause my entire lights to go off and then they would come back on. I have checked around and I found out that the power cord on the back of the unit is very loose. I had a person to come in and look at it, he thinks its the power cord.

My GE JVM1540sp1ss microwave has no power after a power surge. How do I check if theres a fuse without unmounting


My video here will give you disassembly info.

There were two versions of this model made. I've uploaded both schematics.

Your oven should have a technical sheet (which has the appropriate schematic) hidden behind the grille or behind the controller.

You should check the continuity of the fuse (on the noise filter board), the "bottom TCO," the "MGT TCO" on or near the magnetron, and the "cavity TCO."

The first two can usually be checked without taking the oven down but the cavity TCO can only be accessed by removing the oven from the wall, then removing the outer cover.

Also look at the circuit board next to the small transformer for the varistor. If it's charred, burnt, or split, you will need circuit board repair, which I can do for you.

You can find your installation instructions here.

More questions? Contact me directly here.*

* always include the full model number and FCC ID number from the label on / in your microwave (or a clear photo of the tag)

The main fuse may be intermittent, causing complete power failure, the other possibility is a defective door switch not operating properly, or loose plug in the power feed, I suggest a technician to take closer look at the system because this could prove tricky to find the culprit.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

It sounds like a sticky door switch. There are several switches operated by the door latches to keep the oven from operating with the door open. It's possible someone got a little too rough when closing the door, which can cause misadjustment.

Since the oven is so new it will still be under warranty, though. Why not let GE fix it? You just need to tell them it's not working properly. First call the retailer where you purchased the oven. If they arranged installation they probably also handle service. Otherwise you can contact GE's customer service as instructed in your owner's manual to find out how to handle the repair.

You will need to replace the control panel, better off to just replace the oven.

GE Microwave - Power Cord Appears to be Dead


Most microwave ovens are equipped with an internal fuse. This is typically located where the power cord enters the cabinet. The cabinet will have to be opened to verify the fuse.

The magnetron is not directly attached to the power source, it has to be stepped up in voltage significantly, either through a transformer or inverter.

It is usually best to have professional tech check the fuse for operation. Most shops will do this for a small fee if you drop the unit off yourself.
