When you’re in the middle of winter in Northeast Ohio, you don’t want to get caught without heat in your home. The same applies in early spring, when the lake-effect weather can still require home heating well into April. If you suddenly notice your furnace is blowing cold air or just not working at all, find out why in a hurry. Here are a few things you can check yourself before calling a service technician to find the problem:
Electric Furnace Problems
- The most obvious issue might be loss of power, for instance following a local power outage.
- Check the circuit breaker that the furnace is tied to – is the fuse blown, or has the breaker tripped?
- If there’s a reset button, try resetting according to the manufacturer’s instructions.
- Check that the thermostat is working properly – set it five degrees higher than normal, and wait to see if the heat kicks on again.
Gas Furnace Problems
- Check the appropriate circuit breaker – is the fuse blown, or has the breaker itself tripped? A blown fuse will have a darkened or discolored look.
- Is the thermostat working properly? Is it set too low, so that it doesn’t call for heat?
- Check to see if the natural gas or propane supply valve is closed; the valve should be parallel to the gas line.
- Make sure the pilot light in an older furnace has not blown out.
- If your furnace has electronic ignition, check for either hot surface ignition problems, or intermittent pilot ignition problems.
Many of the issues above are easily handled by the homeowner; for instance, resetting a tripped circuit breaker, replacing a blown fuse, re-lighting the pilot light, pressing the reset button and setting the thermostat much higher as a test. But not everyone feels comfortable working around gas-powered appliances, or electronics either for that matter, so if you’re facing something that makes you uncomfortable, by all means contact your trusted service repair company for help.
