Question about GE JVM1440 Microwave Oven

1 Answer

Everything sounds like it is running but no heat. You can hear a hum, so it appearsthat the magnetron is working (not sure though). Would a fuse be blown, even though it sounds like everything is working properly? Please help me. Thank you. Ron Rak email: ronfrak@yahoo.com

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

In some models there is also a very helpful "mini-manual" hidden inside the unit behind the control panel.

Model MH7130xez won't heat. everything else works. the clock, timer and lights. does this model have a fuse?


if unit won't heat, then there is a problem with either the magnetron or the diode. if its the magnetron, the microwave will sound almost normal. if its the diode, it will make a humming sound

Will not heat up food everything else is working


could be 1 of 2 problems. could be simple as a bad diode, or could be a bad magnetron. the microwave tends to make a humming sound while heating if its the diode. If the microwave sounds normal but just not heating then the magnetron is bad and needs to be replaced.

Does not heat up food everything else is OK i think that the rack touch the door when i was using it


Double check and make sure that the rack did't scratch the paint inside the cavity. Could be two possible reasons for it not to heat. Could possible be the magnetron or the diode. Normal when the magnetron goes bad, the microwave will still sound almost normal, bit just wouldn't heat. when the diode goes bad the microwave tends to make a humming sound when turned on

Wont heat. Everything else seems to work. I notice a HUMMING noise while it is opperatiing


A loud humming or buzzing noise would indicate a short on the magnetron circuit, the part that heats the food. These can be expensive to repair since the cost of the magnetron can be as much as a new oven. Get a few estimates before deciding whether to repair or replace.

Everything works but it doesn't heat up the food. What could it be?


The part that generates microwaves that heat the food is the magnetron. Typically when the magnetron fails, it shorts out. When that happens the oven will produce a loud buzzing or humming sound. It typically not worth the cost to replace the magnetron, because it is almost as much as buying a new oven.

Microwave won't turn on


When you say that the microwave won't turn on, can I assume that you mean that the food does not heat up! If that is the case, the problem lies with the magnetron circuit. This circuit consists of the transformer, rectifier and the magnetron, the part that generates the microwaves to heat the food. If it is the magenetron, then it probally not worth fixing since the cost to purchase the magnetron is almost as much as a new oven. To diagnose if it is the magnetron that has failed, when you turn on the oven, do you hear a louder that normal hum or buzzing sound? If that is the case, then it means that the magnetron is shorted and needs to be replaced.

Hope this helps.

Microwave does everything that it is supose to do just that it does not heat and the noise to heat increased. This happend yeaterday.


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Won't heat, works otherwise


It's likely to be the magnetron or a bad connection on the FA terminal of the magnetron, but it may be a bad connection or relay on the control board. This is a page showing how a microwave oven works. A detailed, illustrated explanation. http://www.gallawa.com/microtech/how_work.html If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383 Also, this model may have a "mini-manual" / tech sheet inside which is very helpful in troubleshooting.
