SYMPTOM

Heat, Cool or Fan Runs

Constantly

CORRECTIVE ACTION

Check each wire connection to verify they are not

shorted or touching together. No bare wire should

stick out from under terminal screws.

Try resetting the thermostat as described on page 31.

blower fan will cycle continuously whether the

heating or cooling system is running, press the FAN

button until AUTO is displayed. If the condition

persists, the manufacturer of your system or service

person can instruct you on how to test the Heat/Cool

system for correct operation. If the system operates

correctly, replace the thermostat.
