    dave brown Dave, Unfortunately a bad dealer will leave the worst taste in your mouth. I don't know if Nevada is like Texas and you are stuck with the dealer due to franchising laws, unlike auto's which are take it to a factory dealer. Hopefully GD will get back with you and help.

      Ok, this is a stretch but thought I would chime in since I have "some" experience with this issue. The thermostat is a simple temperature controlled device in which it uses a thermistor (temp probe) to open/close a contact based on a variable resistance determined by the position the control knob is in. If what you're claiming is correct and the compressor is running constantly, you should be able to disconnect the output control of the thermostat and turn off the compressor to validate this theory.

      I used your picture of the T-stat and marked it up:

      Blue line = temp probe
      Red line = Incoming power
      Green Line = switched power (controlled by T-stat)
      Black line = Ground

      Here are a few tests you can do with the Thermostat in place:

      1. Confirm the temp probe is physically located inside the fridge compartment.(if it is not, the compressor will run constantly due to incorrect temperature reading)
      2. Confirm that the "RED" line is in fact your incoming power.
      3. Confirm that the "BLACK" line is in fact your ground.
      4. Confirm if the compressor kicks off when you disconnect the 'GREEN" line (it may be on a timer and may not shut off immediately so give it up to 2 minutes)

      Here are a few tests you can do to bench test the thermostat if you have it out of the fridge:

      1. Connect a DVM to the input (RED) and switched output (GREEN) and check for continuity while adjusting the thermistor (i.e. temp control knob). You should be able to see it open and close the switch on the DVM. (note: you may need to put the temp probe directly on a piece of ice to get it to open the circuit based on the control knob position)
      2. If above test works you know the thermostat works and the issue is not the thermostat itself.
      3. If above test does not indicate that the the thermostat cycles between an open to closed condition on the DVM when adjusting the temp control knob, you have one of two issues:
      3a. The thermostat is defective
      3b. The thermostat is wired incorrectly. Repeat step "1" above, but this time check reading between the input "RED" and the unused connector on the thermostat. If this does not resolve the issue, the thermostat is defective.


      If you can perform these tests and report back your results, it will help in troubleshooting the issue.

        Ok, so thanks for the marked up picture and directions for problem solving. Here's what i found out.
        When testing the thermostat alone (disconnected) but with its' thermistor still in the fridge i get a closed and open circuit with the setting almost to the "off" position, exactly like the original thermostat.
        When testing the thermostat alone (disconnected) but with it's thermistor outside of the fridge i get a closed and open circuit with the setting almost to the "off" position, in the same position as if it was in the fridge proper.
        When testing the thermostat alone (disconnected) but with its' thermistor on a block of ice i get a closed and open circuit with the setting almost to the "off" position, same as above.
        there's a fine spot where if i turn it slight toward colder the fridge comes on, if i turn it slightly toward the off position it turns off. so there's no range no matter where the thermistor probe is set, warm or cold
        If when normally using the fridge i turn the thermostat down to where it just shuts off, it never comes on again... it's either on or off. this is the problem and this is a replacement thermostat. But the original did the same thing.
        Voltage readings:
        my black wire (your green) reads +4.75 volts across to the blue wire (your red)
        my black wire (your green) reads +4.75 volts across to the green wire (your black)
        my green (your black) across to blue (your red) reads 0 volts
        it appears my black wire is +4.75 volts, the diagram reads green as being the ground
        disconnecting the green wire had no effect on the fridge

        Lastly, it's hard for me to tell if the compressor or cooling fan is coming on or off as the only difference i ever hear is the loud fan noise (300 herz) that comes from the grating at the bottom outside of the fridge comes on and off when i play with the thermostat.


        i have left a message and emailed my dealership again... i don't get any reply, again. This time i was requesting a manual to the Furion thermostat so i could know how to operate it.
        I have resigned to the fact that i'm on my own with this 265BH and all the appliances have major issues. So i appreciate anyone who offers ideas on this forum.

          Dave,
          So if you duplicate the tests shown in this video by Joe's RV Tech DIY, what are the results? (Is the thermistor similar to the one shown in the video?)
