Exclamation Thermostat problem

We are having an issue with our air conditioning. The thermostat seems to read 6 to 8 degrees higher than our remote wall thermometer and when you set the temperature the unit runs for an extraordinary amount of time. And regulating the inside temperature is almost impossible. The thermostat is located on the same wall as the side of the refrigerator and electrical converter. It is on the side of the refrigerator and on a corner wall (see photo). Could heat from the refrigerator and converteror air circulation be a problem. This problem exists with both the original manual thermostat and the RVP digital thermostat that we replaced it with. Any Suggestions?

Have you felt that wall to see if it feels warmer, or even held a thermometer to it to see if it's warmer. From the looks of the location I'd say that it certainly could be gaining heat from both the fridge and converter.

If the wall does turn out to be warmer, you could stuff some insulation in the wall behind the t-stat and see if that helps. I'd suggest a vented standoff for the t-stat, but it looks like it'd be a head knocker if you moved it out very much.

Heat from fridge

Had the same problem. I used longer screws and placed 3 metal washers between the thermostat and the wall. It is a little hard to do. But place scotch tape around the washers so you can get the screws through the washers. This moves the thermostat housing away from the wall, prevents heat transfer.

You can use any thing for spacers, just so you can move the thermostat away from the wall.

That is three washers. on each screw.

Make sure the hole the wires run through is filled also with caulk or spray foam to keep the heat from coming in. My wall had insulation in it so it does not get to warm on the outside of the wall
