    Air-bev BM23 stopped cooling need help please

    I'm not sure what happened but my bm23 compressor will not start. The evaporator fan runs constant but nothing else happens. I've tested the overload to see if that had shorted but it's ok and I've also changed the start relay still no go. I'm leaning towards the thermostat maybe being the issue? My question is could I just jumper it and if that is the issue it should start the compressor? If that's not the issue is there anything it could be? Any help is greatly appreciated thankyou

    Also sorry in advance if I posted this in the wrong section

    You mention the evaporator fan runs - it should. The question is, does the condenser fan down by the compressor run? It should be running any time the compressor calls for power. If it is not you need to check to see if you are getting power to the compressor & condenser fan. If you don't have power then you can look to the temp control and yes, you can jumper the leads at the control making sure they are touching nothing else. Should the compressor start while the control is jumped, you need a new control. You could also just test the control with an ohmmeter by taking the wires off the control & cycling the dial back & forth to see if the control opens & closes.

        Did all the tests with a multimeter and the thermostat failed the ohm test. Jumpered it and plugged it in and everything fired up. Thankyou iceman my next question this thermostat looks real old any suggestions on which thermostat to replace it with should I try and trace down an original or after market one? Any suggestions thanks again

            Thanks for your help iceman, found a local dealer that had a a12-700 and installed it. My BM23 is back up and running. Thanks again
