GE microwave jvm1440bh04

When starting a cooking cycle, the cooling fan kicks in for 2-3 seconds and then cuts out. The fan is still turning ,but not at the high speed that you normally hear when a cooking cycle is on.

    Does the turntable turn at the correct speed during this time or does it slow, too?

I would say the cooling fan is failing. It is very critical to protect the magnetron from overheating.

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

There should also be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

When door is shut some type of internal fan kicks on...


Hello Derrick Baker - Typically no fan should come on without starting the microwave. There is one exception! For an example, if the microwave becomes too hot from something that is cooking on the stove below the microwave, the fan will come on and will cycle off once the bottom of the microwaves cools back down. If the fan is turning on when the door is closed, more than likely, a door switch as failed. At this point, I recommend connecting with a certified technician to move forward accurately to assist with the repairs.

Ge pvm2070smss shuts down


It may be a noisy magnetron if the failure occurs in a second or two of hitting "Start" to begin cooking.

See this FixYa solution. even though your model number is different.

Otherwise, if the internal cooling fan is not running when you are cooking, it will shut down after 30-60 seconds or so and stay off until it cools back down.

I have a GE Spacesmaker model #JVM1440BH04 that came on by itself and can't be shut off unless the door is opened. It does not seem to be cooking since nothing heats up unless the cook start buttons are...


The problem is in one of the door switches, "it is defective" this is a highly dangerous situation and should be checked immediately, the microwave oven should unplugged until a appliance repairman looks at it.

Constantly runs but does not heat


The circuit board is faulty. It should be covered under the warranty. Call GE or the place of purchase.

No power to GE Spacemaker Microwave


I have model GE Microwave serial # JVM2070SK02. I start to cook something and it shuts off 5~10 seconds. Keyboard is still lit up, but no clock, fan, light and you cannot operate anything on the key pad. Unplug the unit and it resets. Sometimes it cooks, sometimes it doesn't? It is getting more frequent with the shutting down problem?

No fan noise when cooking.


The internal cooling fan is critical. It comes on automatically whenever the oven is cooking.

If the oven is used without its working properly, the magnetron can be destroyed very quickly.

(This of course is different from the hood vent exhaust fan, which you can turn on and off at will)

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.

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

In some models, the motor itself is bad. In other models, it is a bad relay or connection on the control circuit board.

We regularly repair these control panel assemblies for customers nationwide with our guaranteed $39.95 service in about a week.

Feel free to contact me directly (with your model number) for more information & help.

GE JVM1870 Spacemaker Microwave Fan Malfunctioning when Cooking


There are two different fans in this model, as with almost all over the range microwaves.

One is the hood vent exhaust fan, which you can turn on and off at will, and which should always be on when cooking on the stove top.

This fan does not automatically come on when you cook with the microwave.

The fan which should always be on (automatically) when you are microwaving is the internal magnetron cooling fan.

If the cooling fan fails, the magnetron can overheat and the thermal cutout (TCO) / thermostat will open, killing the power to the oven. Ideally, this protects the magnetron from being destroyed.

If the thermal device is a thermostat, it will reset when it cools down, and the oven will work.

If the thermal device is a true thermal fuse, it is a one-time device and if it blows, it will have to be replaced.

If your cooling fan is bad, it needs to be replaced before using the microwave.

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

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.

Microwave Buzzing, Still Heats, but Turntable And Fan Not Working


This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.

Microwave Buzzing


It is not safe. If a microwave oven cooks without the cooling fan running, then your magnetron will soon overheat and be destroyed. At our Web site, we have important safety information plus information on diagnosing and replacing door switches. Our site is linked at our listing here on FixYa: http://tinyurl.com/yzjozk If it;s not a door switch, then it may be a problem (such as a bad relay) on the control board. We repair these nationwide for $32.50 postpaid in most cases, and you can find out more through that link, too.
