Troubleshooting

Symptom	Possible Cause	Corrective Action
No Heat/No Cool/No Fan	Blown fuse or tripped circuit breaker. Furnace power switch to OFF. Furnace blower compartment door or panel loose or not properly installed.	Replace fuse or reset breaker. Turn switch to ON. Replace door panel in proper position to engage safety interlock or door switch.
No Heat	Pilot light not lit. Loose connection to thermostat or system. Thermostat or heating system requires replacement or service. SYSTEM Switch not set to HEAT.	Re-light pilot. Verify thermostat and system wires are securely attached. Your furnace manufacturer or service person can describe how to test the heating system to verify it is operating correctly. Set SYSTEM Switch to HEAT and raise temp above room temp.
No Cool	Loose connection to thermostat or system. Thermostat or cooling system requires replacement or service. SYSTEM Switch not set to COOL.	Verify thermostat and system wires are securely attached. Your cooling system manufacturer or service person can describe how to test the cooling system to verify it is operating correctly. Set SYSTEM Switch to COOL and lower temp below room temp.
Heat, Cool or Fan Runs Constantly	Possible short in wiring. Possible short in thermostat. Possible short in heat/cool/fan system.	Check each wire connection to the thermostat to verify it is neatly looped under the terminals. No extra wire should stick out from under the terminals.
Furnace Cycles Too Fast or Too Slow		See Step 5, Adjusting the Anticipator. The anticipation setting is the only adjustment that effects the heating cycle rate.
Cooling Cycles Too Fast or Too Slow	Poor thermostat location for sensing room temperature. Cooling system over or undersized. Excessive Current draw influencing thermostat.	The cycle rate for cooling can not be adjusted. The location of the thermostat, size of the Cool system and current draw can influence the cycle rate. Contact a local service person for suggestions.
Thermostat Setting and Thermometer Disagree	Thermostat thermometer setting requires adjustment.	The thermometer can be adjusted by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting.
