Microwave won't heat food but the fan & lights come on & the plate moves around. What will I do to get working again?
See this cuases and fix it. God bless you
Microwave Runs, but no Heat OK, get ready, this micrwave oven
repair can take some time. This is where you must be able to read a
wiring diagram and do some "live" checks on parts. First easy check is
to make sure power is coming off your control board at the MW relay.
Make sure of the wires and test here, if you have 120 volts at this
point, you have ruled out a lot of parts that could be the problem. You
have now ruled out any switch problems, control board problems, or a
thermostat or 2.
If you do not have power from that MW relay on
the control board, you must trace the wiring back to see if the proper
voltage is going through your switches, any thermostats, and arriving at
your control board. Your wiring diagram on your sheet will show you
where and what to test. Below is a general switch test troubleshooting
guide.
If the proper voltage is coming into your control board and you are not
getting voltage at the MW relay, then you need to replace the control
board. If voltage is interupted by a thermostat or switch from your
testing to the control board, then replace that part.Now, testing from the MW relay on to your transformer, high voltage capacitor, magnetron, and diode. Do not
do any voltage reading from the secondary side of the transformer on,
this can be a deadly microwave oven repair if you do not follow
directions. This can result in electrocution and the
"blowing-up" of your voltmeter, only do OHM testing with the power off
and the capacitor discharged. Someplace in this circuit, usually before
the transformer, you will have another thermostat to test. It is
usually mounted on the magnetron. Do a quick OHM test to see if it is
open or closed.
Now to test either the transformer, high voltage
capicitor, magnetron, and diode, you must test each part separately. A
good rule of thumb, if your capacitor is bad, change the diode also.
Another note, if you are working on an OTR model and you have determined
to be one of these "heating" circuit parts, you can not test these
parts until you take the unit down. If you don't have the parts with
you and you have to order them, order the magnetron, capacitor and diode
and you will have a 90% chance of solving the problem. If it is an
older microwave, order the thermostat also, most times you can return
un-used, un-opened parts. Check with your parts supplier. This way you
only have to take the unit down once.
To test these parts, scroll
down this page and you will see a chart with component tests. Follow
the instructions to find which part(s) are defective in your microwave
oven repair.

(If you need more help than this, please reply back with your model number)
It's probably a bad door switch or door switch mount.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch
or mount trouble can be caused by slamming the door or by opening the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab can be hard to see, since it is under the
bottom edge of the switch.
If you or someone you know decide to look
into it, we have critical information on safety, disassembly and door
switches at our site, and our link is at our listing here on FixYa:.
If you only need a switch, you can order one from us for $5 postpaid.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
SOURCE: Goldstar MV1501W not heating or turntable, light/display does wrk
micro switch is bad .remove top vent cover 4 screws,after removing plastic vent panel you will see 1 screw above display time window,remove this screw and lift up the complete button time control panel slightly and pull towards you to remove.there are 2 connections on this panel 1 is a 12 pin connector and a 2 pin power connection remove both put control panel aside.now there are 3 micro switches where the door pins close into the oven lock,remove 2 screws that hold the micro switch housing,on the bottom of housing you will see a small clip gently pull to the right and push back to remove .there are 2 switches on bottom of it and 1 on top. the 1 on top is normally open and closes when door is shut but like mine it stayed open and resulted in (light s display but no turntable)soon as i replaced upper microswitch it runs perfect.i hope this helps .MODEL MV1501W GOLDSTAR
SOURCE: It is running, but doesn't heat the food.
I had the same thing happen to my microwave and the Magnatron was the bad part. There are some things that you can check and I would be glad to help. I bought the parts for around $70.00, but mine was a built in unit.
Let me know, I will help.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I have helped you, please help me, and rate this suggestion a the highest FixYa rating (Give it Two thumbs up). If not then please comment to this post and I will try to help you further.
Thank you for your support.

you can take it into a local repair shop but it might cost more to repair it. Looks like you can replace the unit for 150 to 250 sears carries this brand.
