First off I have repaired this refrigerator I it just mind boggled me so much I want an explanation if possibel.
The refrigerator wasn’t cooling and when I checked it the evaporator fan wasn’t running. So I check voltage on the fan (with it sill connected) and got 120V, bad fan correct. Wrong, I ordered the fan (I don’t stock many frigedaire parts) went back and installed the fan. Still will not run, so I got my meter back out and checked voltage sill 120V.
The compressor was running so that ruled out a house-wiring problem. This is a simple 120V fan with only two wires. I was also thinking that my meter may be going crazy so I tested it in the wall plug and got the same reading as when I put it on the fan.
So I took the fan out and directly plugged it into a wall plug and it ran like crazy. Looking at the wiring diagram the main board (adaptive defrost control) is the only thing it could be.
This gets even better. The older man that works for us (basically retired) with 40 years appliance repair experience said he didn’t believe me so he wanted to go with me.
So when we went back just to prove I wasn’t crazy I put the fan in without replacing the main board. The fan didn’t move, so I check voltage across it and got over 250V. I had the meter on the 250V scale and it pegged the needle. At first I thought I had accidentally set the meter on ohms but that wasn’t the case. Again thinking my meter was crazy I tested voltage in a wall plug and got 120V. Mind you the motor isn’t even attempting to run.
Replaced the main board and the fan took off running and the voltage across it is now 120V. This thing blew my mind. I though I knew something about appliance repair.
