Frigidaire microwave professional series

I have a Frigidaire Electrolux Professional Series Microwave. Model CPLMB1866CCA - 1.5KW with max power output of 1100 watts. Although all functions work, it is only partially heating. Example - What would normally require 2 minutes of heat would need to be heated for 5-6 minutes. Is it the magnetron, power diode, high-voltage capacitor or other? Not attempted to fix as yet. I have fixed my other appliances in the past (ie replace parts on digital stove, washers, dryers etc..). Is replacing a magnetron, power diode, or high-voltage capacitor difficult to do or requires a technician?

Yes, it could be the Magnetron. If the unit is out of warranty, you can try to remove the rear cover (make sure unit is unplugged) and see if there is a blown fuse in the section that powers the Magetron. They are not too difficult to replace. MCM Electronics sells them and you can call them with your model and they can find a replacement for you will be able to see how much it will cost.

The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

SOURCE: Maytag MMV5156AAS Microwave won't heat and has hum/buzz.

A failed diode isn't the most common failure, but it happens. And sometimes it's due to bad magnetron or a bad connection.

If the capacitor fails, it almost always shorts, which results in a blown fuse whenever you hit "Start" to run the microwave.

The magnetron on this model should have a 5-year warranty, in case that's relevant. Your owner's manual is here.

We have the service / repair manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

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

There should also 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.

You can find helpful exploded view diagrams and order parts here.

SOURCE: How do I install a replacement Frigidaire over the

Remove everything from the inside of the microwave, (such as glass tray). Unplug the microwave, probably in the cabinet above. There are two screws in the cabinet above the microwave, near the front, that supports the front of the microwave. The back is hooked on a mounting plate attached to the wall behind it. An assistant is a good idea though this can be accomplished alone. It is best to move the stove out, if you are going to try alone. Please be carefl there is considerable weight to support here. Support the front of the microwave while the two screws are removed in the cabinet above. Slowly tilt the front of the unit down until you can pull the cord out of the bottom of the cabinet. With the front still tipped down, lift the back from it's support and remove it.

Frigidaire professional series micro wave is making a grinding noise


Good Morning friend, thanks for your post!

Good Morning friend, thanks for your post!
From the information you have provided your Frigidaire microwave is making a grinding noise. This could be a possible problem with your motor or magnetron. I would advise to remove the plate on the inside of your microwave and check to assure no dirt or debris is holding the movement of your bottom plate. You may want to perform a reset on your microwave and you can do that by disconnecting power from it for roughly ten minutes. If that does not work you may need to have one of the electrical components replaced on the inside of your microwave and I would recommend having a professional technician out to perform repairs. This will help to avoid any future issues or personal injuries. -Matt

My plmv169dcd stopped working,looks like it has no power, but there is power at plug in. is there a reset button>


Not quite enough information. But, there is no reset button. Open unit check fuse. test all 3 door switches. They are the number one cause of problems and can take out the fuse or not. Other than that it will take more trouble shooting to find the problem

Frigidaire Mod: FGMV174KFB Door won't latch


Good Morning Friend,

I understand the door will not latch on your Frigidaire microwave, model# FGMV174KFB. Typically, this would not be a do it yourself repair, as you are working with your microwave, and there are no step by step repair instructions. I suggest contacting your local authorized technician for further assistance. They have been trained on your appliance and should be able to fix the latch on your door with ease. Hope this is helpful.

-Best Regards-

Trying to remove to two long screw holding out of top. still being held in back help


We have a Gallery Frigidaire series "professional" model and I encountered the same issue where it would tilt forward but not come of wall. Ours had three long bolts thru top cabinet after removing them it tilted but would not come out. I could not find any levers or other bolts holding it to bracket/wall. Turned out it was just the electrical cord routed tightly though upper cabinet that was holding it once we fed slack thru hole it came right down. Hope this helps, Bill C from Babylon NY
