Furnace Troubleshooting Guide to Solve Common Furnace Problems

Your furnace is crucial for keeping your home and family healthy and comfortable when Old Man Winter arrives. Without a working heater, you would have to endure torturous nights and mornings with lots of layers. It’s a good idea to know how to solve common furnace problems in a pinch and perform basic furnace troubleshooting.

Proper heating maintenance in the fall of every year can prevent most furnace problems in winter. Unfortunately, like any complicated pieces of machinery, furnaces eventually develop problems and require repairs and/or replacements.


Check Furnace Filter

Your HVAC and duct system has been specifically designed for your home. TO facilitate airflow and energy efficiency, make sure you replace dirty air filters on time (30-90 days) and check your ducts, vents, and registers. Many furnace problems can be traced back to a dirty air filter.

InspectDucts, Registers, and Vents

Regardless of what you have heard about saving energy by closing off vents and registers in unused rooms, this is NOT a good idea. Go around your home and make sure all of your vents are fully open and unobstructed. Check under rugs and behind furniture and drapes.

Furnace Troubleshooting Recap:

If furnace cycles on or off too frequently:

1. Adjust thermostat anticipator

If you have a manual, electromechanically thermostat, you may need to adjust the anticipator to fix a furnace cycling problem. When making anticipator calibrations, only move one setting at a time.

Try moving the anticipator to the “longer” setting if your furnace has troubles reaching the desired temperature. After each adjustment, wait a couple hours to see if the problem is solved. Most anticipators work best when set between 0.2-0.8 amps.

2. Clogged Filter, Wrong Thermostat Setting, or Improper Airflow

Some of the other causes of furnace problems mentioned earlier can also have a negative impact on your furnace cycling. If your furnace is turning on or off too frequently, make sure you have a clean air filter, duct and registers are unblocked, and a properly set and programmed thermostat.
