While I have had my thermostat out annually for winterizing, I have never cleaned it. So I decided to give it a try.
|Half way clean, after 2 days soaking in vinegar|
I also wasn't sure what temperature rating my thermostat was rated for so I tested it by boiling it.
The thermostat started opening around 125 degrees Fahrenheit and was fully open around 160 degrees.It was approximately 1/4" open at it's fullest. I'm not sure if either of these are measurements are within spec because I can't find a good reference online. If anyone knows, please comment below.
I'm not sure if my dirty thermostat was the cause of my cooling issues but it couldn't be helping.
