Thermostat Ct51
The CT51N1007 (analog) thermostat won't turn off when temperature reaches desired setting. Heating continues until we turn if off manually. We purchased it one year ago last week (of course). We are not here during the summer so the thermostat has only been used for 6 months.
Please advise what we should check. Thank you.
