Question about Frigidaire PLMV169DC Microwave Oven
Just completely went blank. cant find any fuse can you help me.
This is a possibility. TDK makes a number of components. Is there a label screened to the board saying what it is? It is always possible that the board is bad. The transformer can be tested. All transformers are a/c. Try this first: Unplug the unit. Using a multimeter set on ohms, low scale, check across the plug. You should get resistance. If op4en (no needle movement...no change from open probes), it is a fuse you haven't discovered or the transformer. Get to the wiring for the transformer. Test across the primary (110V) side. Some resistance reading now indicates a bad fuse. Open circuit is a transformer problem. Disconnect the transformer on the other side from any board...at least one connection. Perform the same test. You should have some needle or numerical reading. No movement...bad transformer. I hope this helps. If not, get some assistance.

They are always inside the keypad enclosure. If they are on the board, they are labeled with something that says "4A" or something like that...they may not look like a fuse. Did you find the sensors?

Jl, first, are you sure that you have power? Plug something else in to check. Also, unplug the unit, wait a full minute and repower. Sometimes this resets the units. Second, fuses are generally located inside the keypanel area. With the unit unplugged, remove the screws holding the panel on. Inside, you will find at least one fuse. You will also find thermo sensors. They are black, about the diameter of a dime and 3/8 inch thick with two wires coming out of them. Check them for continuity.
