ELECTRICAL DATA
THERMAL DATA:
Symptom | Possible Cause | Corrective Action |
No Heat/ No Fan (common problems) | 1. Blown fuse or tripped circuit breaker. 2. Furnace power switch to OFF. 3. Furnace blower compartment door or panel loose or not properly installed. | Replace fuse or reset the breaker. Turn the switch to ON. Replace the door panel in the proper position to engage the safety interlock or door switch. |
No Heat | 1. Pilot light not lit. 2. Broken or melted anticipator wire. 3. Loose connection to thermostat or system. 4. Thermostat or heating system requires replacement or service. 5. System Switch not set to Heat. | Re-light pilot. Excessive current or dead short in the system. Have a qualified service person check the system before replacing the thermostat. 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. If the heating system is capable of operation and the no heat condition persists, replace the thermostat. Set System Switch to Heat and raise temp above room temp. |
Intermittent Heat | 1. Furnace Lock-Out Condition | Many furnaces have safety devices that shut the system down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance. |
Heat or Fan Runs Constantly. | 1. Possible short in the wiring. 2. Possible short in thermostat. 3. 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 Narrow or wide temperature swing | See Step 5, Adjusting the Anticipator. | The anticipation setting is the only adjustment that affects the heating cycle rate. If an acceptable cycle rate is not achieved using the anticipator contact a local service person for additional suggestions. The location of the thermostat, size of the Heat/Cool System, and current the draw can influence the cycle rate. |
Thermostat Setting and Thermostat Thermometer Disagree | 1. Thermostat thermometer setting requires adjustment. 2. Thermostat setting lever requires calibration. | 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. For calibrating the setting lever contact a local heating and cooling service person. |
Adjusting Thermometer | 1. Thermostat thermometer disagrees with other room thermometers. | The thermometer on the thermostat is accurately calibrated at our factory but you can adjust it by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting. |
