Troubleshooting Heating Problems
Make sure thermostat is in the heating position and it is turned up above room temperature.
Make sure filter is clean.
Make sure on/off switch on the side of the furnace is in the on position. Also, check circuit breaker.
Make sure drain hose is unrestricted, if you have a +90% furnace.
Make sure the white outside vent pipes are unrestricted, if you have a +90% furnace.
Make sure the bottom cover of the furnace is on securely (blower access panel).
If the above fails to solve problem, call for service.
Furnace repair is a job most of us would be happy to hand over to a professional.
