Last week we had some freezing temps (unusual for our area and even more unusual this time of year). My elderly mother can't stand cold so she turned the heat on but when the weather warmed up a bit more it won't cool anymore. It heated above the level it was supposed to heat to and now it won't cool off. The house is much warmer than the outside. It's like the thermostat is not communicating properly.
I read that the fan will only make things hotter if the coils are still warm/hot and it will only circulate hot air so my 3rd step (1st step was switching to Auto, 2nd to Cool-- to no avail) was to hit the button to turn the fan off. It didn't work. Fan would not turn off even after I left it for several minutes. I mashed the button multiple times and the only thing that changed was the display. I flipped the breaker on and off in the hopes it might reset things. Nope. I eventually just turned the whole thing to Off. Which did seem to work as far as I could tell. I checked the filters, poured bleach down the condensate line, capped it back up tight, played with the settings on the thermostat-- only thing that seemed to work was turning it off and when I turned it back on the fan came on (even when set to off).
I decided to pull the cover but apparently this thermostat has the entire kit and kaboodle attached to the cover and there is a wall plate with wires that stays on the wall when it is pulled off. It has 7 wires. I traced the wire from mid-level on the furnace up to the ceiling, down the wall, and into a hole near the thermostat. I took pictures and then popped it back on. After that the fan will turn on and off when I push the button but nothing seemed to happen when I switched between heat, cool, and emergency heat modes. Only thing that worked was "off". I currently have it set to cool, but last I checked its still at 87°F and highest it is supposed to allow is 72°.
The outside compressor is not kicking on so I don't know if it blue a capacitor again (we just replaced both capacitors AND the fan motor a few months back) or if there's something wrong with the thermostat. It's over 10 years old. I think we had it installed in 2009 or 2010.
I really hate this thermostat because it is hard to see unless you are at just the right angle and have enough light and even then, some of the writing is too small for me to read without glasses. When I first popped it back on, it went to EMHeat. When I saw this in the picture, I switched to Cool.
It looks like there may be 2 separate cables so I'm assuming some are coming in from the furnace and others are going back out to the compressor? I'm not overly familiar with this stuff. The bracket off to the right on the wall part holds some sort of clear plastic piece with a tab (I didn't take pics) and I'm not sure what it is for. It can be pulled out from the right side.
Any thoughts? I want to replace it with something that I can see more easily and that has good controls.
