Check the thermocouple if you find the temperature variation of the thermostat is more than ± 5.F from the set point. To check a thermocouple, follow this procedure: Note: The Type J thermocouple requires the use of a Type J temperature meter. If a type J meter is not available use a millivolt meter and refer to the tables of degrees/millvolt values following, to calculate the cold ju
