Furnace Repair Checklist
Start by ensuring your thermostat is properly set to signal your furnace to start
1. Check the Thermostat
For Digital Thermostats:
Replace the batteries if the screen is blank. If the screen appears jumbled, the thermostat may need replacement.
Set the switch to “heat” instead of “off” or “cool.”
Confirm the program is set to the correct day and time, and press “hold” to bypass programming issues.
Adjust the temperature to 5 degrees warmer than the current room temperature.
Switch the fan setting from “auto” to “on” to check if the furnace is receiving power.
For Smart Thermostats:
Troubleshooting is model-specific for brands like Nest, Ecobee, Lux, Honeywell, or Bosch. Visit the manufacturer’s website for guidance. Still having trouble? Call Done Right Air at (414) 888-6880 for expert assistance.
2. Examine Breakers and Switches
Ensure your furnace has power by checking your electrical panel and furnace switch.
Locate the breaker labeled “furnace” or “heat” in your electrical panel. If it’s tripped, reset it to the “on” position.
Check the furnace wall switch near your unit and make sure it’s flipped “on.” If it was off, allow up to five minutes for the furnace to start.
If the breaker trips immediately after resetting, leave it alone and contact Done Right Air at (414) 888-6880.
3. Replace Air Filter
Steps to Replace the Air Filter:
Turn off your furnace.
Remove the old filter and hold it to the light; if you can’t see light, it’s time for a replacement.
Insert the new filter with the arrow pointing toward the furnace.
Flat filters should be replaced monthly, while pleated filters last about three months. Mark the airflow direction and filter size on the furnace housing for future convenience
A dirty air filter can cause several furnace issues, such as:
Furnace not staying on or overheating.
Increased energy bills.
Premature system failure due to strain on the furnace.
4. Inspect the Condensate Pan
If water is dripping or standing in the condensate pan, follow these steps:
Check for clogs in the drain (look for a PVC pipe) and clear them if necessary.
For pans with a pump, inspect the float switch. If it’s stuck, call Done Right Air at (414) 888-6880, as you may need a replacement pump.
Look through your furnace’s inspection window for light signals. If you notice anything other than a steady or blinking green light, it could be an error code. Call (414) 888-6880 for professional HVAC service.
5. Check for Furnace Error Codes
6. Clean the Flame Sensor
A dirty flame sensor may cause your furnace to shut off without blowing heat. Here’s how to clean it:
Turn off the power and gas to your furnace.
Locate the flame sensor by following the wires.
Unscrew the sensor, clean it with fine sandpaper or steel wool, and wipe it with a dry paper towel.
Reinstall the sensor and restore power.
If your furnace doesn’t turn on after cleaning, the sensor may need to be replaced. Call Done Right Air for help.
For older furnaces, follow these steps to relight the pilot:
Turn the pilot switch to “off” and wait at least five minutes.
Set the switch to “pilot,” press the “reset” button, and use a long lighter to ignite the pilot light.
Release the reset button once the pilot is lit.
If the pilot light doesn’t stay lit after two attempts, contact Done Right Air at (414) 888-6880 for service.
7. Relight the Pilot Light
8. Check Your Fuel Source
Turn on another gas appliance to ensure your natural gas or propane supply is functioning. If not, you may need to contact your gas provider.
