I ave a Sharp Micro/Convection Carousel II oven. The micro works fine but the oven will not heat up , just stays warm. What part(s) might be causing this and would need to be replaced. I LOVE this unit and not sure if wise to replace parts or just bite the bullet and spend $300.00+ for a new one.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

Assuming your inside light and turntable come on when you try to microwave, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it's probably okay)

If it's within the magnetron portion of the warranty (5-9 years) but out of the original full warranty (1 year), G.E. will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Sometimes they will send you the magnetron to do it yourself.

If nothing else, you can save about $50-75 if you remove it from the wall and take it to a GE-authorized servicer.

You can find a GE-authorized servicer by calling GE Appliance Service at 1-800-848-7620 or here.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.
