if the compressor is a normal 120vac compressor and the start device is a normal PTC start device (not a 3ph inverter unit)

 

i would disconnect the compressors power wires and install a power cord to the start device just to test the compressor and the start device

 

run it for a while with the two plugins , makes sure it gets cold before going further

Thanks for the reply I hooked up the compressor straight to the wall and the device and the compressor run fine.

 

 

 

The file that Regus posted was the correct one. (thank you)

 

Am i right in assuming that on con1 pin 1 and pin 5 should have 120 volts when in test mode1?

 

In the pictures uploaded the white (Pin1) and yellow (pin5) wires, or board markings comp (Pin1) and L (Pin5)

The pin marked comp and neutral should get 120v during test.

 

Looks like pin 1 and3 (Black and White)

 

See page 23 of the manual for details on "test mode"

ok yea they are getting 120v but down at the compressor where the wires come out of the bottom of the fridge there is no voltage.... im lost here ... do the wires go somewhere else between the board and the compressor?

Jumped wires from n to olp  and comp to start device and it runs fine.... assuming there is a broken or shorted wire inside the cabinet somewhere that I can't see? 

 

If anyone else has another explanation please chime in...

Try and measure the wires from end to end with an ohmeter, wiggle them around and see if it makes/breaks the circuit - broken wires are certainly not beyond the realm of possibility

I have to correct this, looking again I see it is pin1 (white - goes to capacitor) and pin 5 (yellow - goes to compressor overload.
