This is my first post on appliantology, forgive me if I get anything wrong.
My name is Joshua and I run a washer and dryer repair business in San Francisco.
I have a customer waiting and I'm kinda stumped.
This is a Frigidaire made Kenmore laundry center, model number 417.97862792
It has a top loading washer and it's the odd sort where the door lock and lid switch have only 2 wires.
How you can detect door closed AND door locked AND power the lock with only 2 wires is beyond me. Though I have to admit that I'm not sure that it detects the door being locked, perhaps it only detects door being closed.
It certainly can detect door closed. The water only fills when the door is closed.
The motor doesn't move in spin or agitate. The water pump works fine. I notice that in the spin cycle the door usally locks but doesn't ALWAYS seem to lock. It DOES detect being open or closed because the water stops.
Later on I noticed that it will agitate in SLOW speed. When it went into the spin part after that, it didn't spin but for the first time there was a very strong ozone smell.
The motor was perfectly silent in both agitate and spin. No vibration, nothing. No smell.
1) The motor can turn easily in either direction.
2) The start capacitor seems to charge when being tested (1st thing to test on the troubleshooting flowchart).
3) M3 to M6 on the motor measure 1.6 ohms. It's supposed to measure 2.4 ohms. But the flowchart has infinity as broken not low resistance. I'm not 100% sure that my manuals are exactly right for this machine. They're Frigidaire manuals not Kemore. This model takes a 3/4 hp,2 speed motor original part 131653300, replacement part 134159500
4) M1 to M5 measure 8 ohms as they should
At this point I checked wiring... The timer contacts LOOK good, no bent cam riders. A couple of the connectors to the timer were very badly tarnished, I cleaned them. The pressure switch seemed to work. I noticed the wire harness connector from the upper half to the lower half had 3 points that where browned. I bypassed those parts of the connector.
Still, it didn't work.
But then I tried gentle. It agitated. I tried again agitated again, but when it got past agitate and the pump came on, I could smell strong ozone from the other room.
I don't have any instructions on how to test the motor directly like I do a maytag. I suppose 120 volts between M3 and M6 and some M1 and M5 does it?
I told the customer that the smell made me think it was the motor, but is that conclusive? I've noticed that flakey switches that go on and off can make a motor seem bad on other (non frigidaire) machines.
What do? I can't return electronic parts once I've tried them. Motor? Timer? Door lock?
What tests did I miss?
I would really appreciate advice before tomorrow afternoon, even if the advice is a phone number where I have to pay money to talk to a Frigidaire tech.
