set thermostat to 250 reaches 150 turn thermostat up comes back on but does not reach set temp or close about 100 degrees off
If u know that ur consistently off by 100degrees Test the ohms on ur rtd probe.
call Cleveland (or if some one knows them off hand) for the value at room temp and u can see if it’s the prob or control board.
Sounds like the probe's off, I've replaced a couple of them.
