Bill No fuses in thermostat or near. Only in the AC units on roof, 3amp fuses and they are good. Share this post Link to post Share on other sites
wildebill308 Report post Posted May 24, 2022 About the only thing I know how to do now is start trouble shooting back from the thermostat to find out where the power is interrupted. Bill Share this post Link to post Share on other sites
jleamont Report post Posted May 26, 2022 Sounds like a cable, the one between the main AC unit and the thermostat. Our coach the bedroom is the main unit and the front is the host. it’s simply a phone cord with the connections reversed. I replaced ours a few years ago, it chafed on the back of the electrical panel. All I had to do was cut it in half, flip the cable over and splice it back together, of course I completed that after I pulled it through the maze of tunnels.

Thinking it is the phone cable but it is wired backwards to what normal phone cabling is so I've got to get connectors reversed to try a new cable. Share this post Link to post Share on other sites

Na, simply cut it a few inches from one end, peel back the outer jacket, flip it over and re splice back together. I.e. don’t match the colors. It was just that simple. All you need are solderless crimp connectors. They are low voltage, no risk of electrical shock. that’s a simple and cheap test to rule out the cable in the wall. I plugged directly into the connection in the rear AC unit and laid the thermostat on the bed to make sure it was correct. Some manufacturers reverse the connections in the female to female adapter in the AC unit so the core is a standard phone cord, not so with Monaco. You could check the colors at each end fairly easily by looking at the plugs, lay the locking tab up and see what the color order is. Share this post Link to post Share on other sites

Took it to Premier RV in Junction City and they found the control board and cable connection to be corroded. Old thermostat works but went ahead and replaced it with the Easy_Start RV one that I had already purchased. Now I have a spare thermostat. Share this post Link to post Share on other sites
