Display screen on my Frigidaire FMV156DCA does not function properly (can't see time). Hihowever, everything else functions great. How do I fix this?

I assume the display is hard to see but otherwise the unit function correctly? I'm going to gear my answer to this issue. If everything on unit functions but just can't see clock and temp. settings, you have a bad display. That's gonna be part #2. I'm not how to upload video but go to youtube and type in Kitchenaid slide in electric control replacement. The top video should give you a good idea on how to change display board out. Good Luck

Two things could have happen to your machine.
One the magnetron is dead and needs replacement.
Second the high tension power which supplies power to the magnetron could have been screwed up and need to be replaced or repaired.
The fact that the fan is not running I suspect it may be a power board issue.

Good Morning Evelyn, thank you for allowing me to assist you!

Here are some simple troubleshooting tips to help replace the light bulb on your Frigidaire microwave, FMV156DCA.

·First, disconnect power to your microwave. This can be done by either unplugging it or at the circuit breaker panel.
·To release cover, remove the screw on the light cover (light cover may become very hot, do not touch glass when light is on).
·Remove old light bulb and replace only with equivalent watt bulb available from parts distributor or the manufacturer directly. Bulbs are also available at most hardware stores or lighting centers. Bulbs larger than 30 watts are NOT recommended.
·Close light cover and secure with screw removed in step 2.

I hope this information proves to be helpful. If you have further questions, please do not hesitate to reconnect.

Hello epinvegas - Try reprogramming the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and restart unit. If it proves to be ineffective, then it sounds like the microwave has a faulty magnetron, wiring failure or control board. Contact a professional to assist with the repairs.

see this causes and fix it.
God bless you
f the microwave will not work at all, make sure power is on at the outlet and test the electrical cord. Test the fuse and replace it if it is faulty. Also check the door to make sure it closes properly. Test and, if needed, replace the fan. If the oven doesn't cook or cooks only intermittently but the display is on, check the door interlock switch, the thermal cutout (see the Applaince Controls Fix-It Guide), and the fan, replacing parts that don't pass the test.
If the oven keeps blowing fuses, check for a faulty door interlock or monitor switch.

This is a strong indicator the magnetron is going to fail, and it is a matter time.

Hi,

There is not a bulb that needs to be replaced. Unfortunately this happens quite often on these ovens and the only way to fix the problem is to replace your entire display control board.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hello,
You can fix the problem by yourself, the problem is from the magnetron (sp), this has to be replaced to make the microwave oven functions effectively......

I suggest you see a repairer but until then when ever it's not in use leave the door OPEN

Kind Regards,

It may be that the internal firmware has become corrupt, or there is a fault on the main processor board, or with some other area that is effecting the system processor, and thus the system is not able to function properly.

Call the service rep for your microwave oven and bring it in for an estimate.
