The control display on my microwave is very dim. Is there any way to make it brighter?

If you had mentioned your full model number, we could have looked whether the VFD is available as a separate part in case your model has a VFD display, or whether the whole control board would have to be replaced.

If your model has an LCD type display, it may be weak LEDs or other failing components in the display backlight circuit.

We regularly repair microwave displays for $39.95 nationwide.

It's pretty rare for a microwave to have a display brightness feature.

Let us know if we can help you further.

I have GE Profile microwave model PVM1870SM1SS and last week while running, suddently it shut off. There is no power, display buttons and stopped running. Please advise.

From the description a major part has failed, the magnetron is suspect because it suddenly shut down in cycle, if the unit is less than 7 years old it probably has a inverter board and tends to fail, also there is the possibility the keypad control board has stopped working. The microwave in my opinion is worth getting checked out and repaired, but it will be expensive.

My microwave has power lights up seems to work but doesnt heat up what could this be?

The magnetron is a common part to fail, but there are other parts that should be considered, if over 7 years the high voltage capacitor and diode, if 7 years or less the inverter board. In most cases cheaper to replace.

The LCD display is not showing the numbers correctly. It looks like the numbers are missing "lines", like an 8 can look like a 3, the 8 can look like a 0, etc. Any ideas?

It is the control board that needs to be replaced. The LCD display is connected to the board. If this is an above the stove microwave the problem was caused by the steam from boiling water on the stove top. you can prevent it from happening again by using the vent fan consistantly.

Sharp microwave oven LCD display malfunctions

Might or might not work. IT worked for me.

This is a common problem. i havent completly solved it yet but this helps.

Be very careful doing this, There is Voltages with AMPERAGES high enough to boil your blood inside a microwave.

I had mine apart cleaning it. Only one number worked on my display. I wiggled and messed around with the wires in the back of the display. And almost every number in the display works again. Hope this helps.

The Control Panel is failing. The Control Panel consists of a Keypad, and a Control PC (Printed Citcuit) Board. You can replace it as a complete unit. Not Cheap!!
Good Luck!

LCD display missing part of numerals

Yes, we repair these displays for $32.50 with a one-year guarantee. Repair Clinic charges $169.35 for the display board assembly. Tritronics (our supplier) sells the assembly with display (part # DPWBFC167WRKZ) for $107.07. On the rare occasions when we actually replace that type of board for our customer (at our cost of only $73.33) we also perform our proprietary fixes on it. We do that so the new display does not also fail in a few months, or even right out of the box! That actually happens!
