I am working on a MAYTAG s/s model # MSD2754grw.
It is not cooling. So I removed the access panel and connected my Old Trusty Annie A-3.
And it would not work. I mean the Annie does not work.
So it is time to go Old Skool, wipped out the old Ohm Meter and read the pin terminals.
All seemed ok.
So I read the PTC Relay and it seemed ok,
Changed the capacitor but that was not it either.
Checked voltages at the PTC Relay and they were good.
The unit does not hum like a stuck compressor.
It just sits there till you hear the overload go click.
Start - Common 3.0 Ohms
Run - Common 6.4 Ohms
Start -Run 9.6 Ohms
No shorts to ground from any pin
PTC Relay 5.2 Ohms
Just for kicks I read the Overload as well, it was .2 Ohms.
