Question about Frigidaire PLMV169DC Microwave Oven
I bought and installed fridgidaire PLMV169DCD model 16months ago. Suddenly its control panel display went off. It came back once after I took out power and put it back but after couple of hrs it again went dead and never worked.
may be the fuse, which is usually located behind the grille or on the
floor of the oven behind the control panel or between the door switches.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
When checking TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall.
You can download Frigidaire / Whirlpool installation instructions here.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
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.
