I have an air cooled frigomatic AV35F with the extra speed control box
. It started cooling
bad, and didnít took up much amperes, but it did start the compressor
. I removed the thermostat, suspecting it, and shorted the terminals on the speed control box
. Since it wonít ever start.
-voltage 12.7 (from a victron 30A charger), green power led on
-no error led signals
-manually shorted thermostat pins on speed control box
-manually shorted thermostat pins on compressor
-checked that the speed control box shorts itís thermostat out wires
-removed 3 pin connector from thermostat, cleaned and reseated it.
-measured resistance across the 3 terminals of the compressor as per the manual.
It seems that the speed box and the mech thermostat works but the control electronics
on the compressor wonít start. However it gives no error messages. And it was working when i removed the thermostat. I canít see any problems electronically, and the manual says the compressor is good if you can measure the same resistance across the pins.
What am I missing?
