Poping GCFI outlet

My norcold N611 is poping the ground fault breaker when it is in A/C mode but works fine in LP mode. Is there a way to check the heater circuit in the fridge?

  • If that is 57.5 ohms to ground you need new heaters. Basically there should be infinite ohms to ground. If that's 58K ohms on a 200K scale then it's somewhat questionable.

    Somewhat questionable??? Well the resistance is a static measurement. AC really involves impedance, changing conditions due to heat etc. But I digress...
  • I guess I need a lesson in OHM Meters. When I unplug the heater wires they read 57.5 with my OHM meter set at 200K. Good or bad?:?
  • It wasn't the gfci outlet. I'm goona try to check the heater now. I guess I just unplug the wires and put an ohm meter from one of the leads to ground?
  • I have even changed a GFCI. I have the lowest "mechanical IQ" ever as evidenced by my posts on this forum. Very easy. Instructions included with the new GFCI. If that doesn't fix the problem, it is only a few bucks to rule out the most likely culprit.
  • I'd change the poping (or is it pooping or popping?) GFCI also.
  • Its the GFCI outlet. Change it and you will be fine. Ironically i just changed one yesterday. They are a real PITA...:(
  • Disconnect the heater wires and use a ohmmeter to check the resistance to ground. It should be well over 24K ohms.
