Ok, there is an in-line fuse that is located inside the unit on the power supply board. if this fuse is damaged, replace it. If this fuse is ok, replace the entire power supply board.

Why does light come on, no motor or cook. Display is good


please follow this steps and fix it. God bless you
  1. Inspect the power cord Unplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switch If your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fuses To determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motor Locate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

Lighting Problem


We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

We're happy to help and we appreciate your thoughtful rating of our answer.

No light, internal fan...then no display


The light isn't a safety issue but I would think that the fan would be.

The fan is designed to remove excess heat from unit and keep it cool. Without the fan, you're now operating the unit under conditions that it wasn't designed for.

With the unit unplugged, try removing the cover and see if a fuse has blown. If so, replace it with the EXACT value of the original.

See if the unit powers up again. Try heating heating up something for 30 seconds to see if the Magnetron is still functioning.

If so, check to see if the bulb is good. Did the bulb and fan stop at the same time? If so, it might be something in common that controls both.

Don't operate it further until you have it looked at. You don't want to cause something else to fail.

Good luck!
