Problem With Honeywell Rth221b Thermostat
I have a Honeywell RTH221B thermostat. When it is set to cool, the A/C never shuts off regardless of the temperature it is set at. It displayed a 61 degree temp when it was set to 74, yet the compressor was still on. Does anyone have any advice as to how I can repair this problem?
