Furnace Repair FAQs Common Problems and Solutions
There's nothing quite like the first morning of crisp fall weather. But then, you go to turn on your heat for the first time this season and nothing happens. You get that familiar pit in your stomach knowing an expensive repair is likely in your future. Well, the good news is that you have a chance of fixing this furnace problem yourself. With a little know-how, a DIY furnace repair is simple. So, keep watching to find out how to fix your common furnace problems before calling the HVAC pros.
CHECK YOUR THERMOSTAT
If you call your furnace company their first advice will be to check your thermostat. Make sure the heat setting is where the slider is. Check the temperature settings. The heat won't kick on unless the home temperature dips below the set temp. Replace the batteries in your unit to be sure the signal to the system is strong.
RESET YOUR BREAKER
Make sure none of the circuit breakers have blown out. Are any tripped? The breakers should all be in the on position. Turn the circuit that controls the furnace off and on again. Note the position when you got to the box. Was it flipped off or was it in the middle? When you flipped the breaker did it stay in the on position? If not, your problem is the circuit itself. Get yourself a digital multimeter and check the home's circuit wiring.
When was the last time you changed your furnace filter? If you don't know, or it's been a long time, this may solve the problem. Make sure you get the correct filters for your furnace. Remove the old filters and make sure there is no debris left in the opening. Insert the new filter and reset the breaker. Filters need replacing every 90 days every month in times of heavy use. Now go back to your thermometer and test the furnace.
NEGLECTED FURNACE MAINTENANCE
Besides the filters, you also need to check the safety switch on the furnace door. Open the furnace door and check for the safety switch to pop out when you close the door. If it isn't working you can install a new safety switch yourself in a few easy steps. Make sure the entire area around the furnace is clear and clean. As tempting as it is to use the area for extra storage, it's not worth the risk, as cluttered space makes the furnace have to work harder.
BLOCKED HEAT PUMPS
Does your unit vent to the outside of the house? Go outside and check that the vents are free of leaves and debris. Clear away any grass or leaves from the heat pump as well. Before your main heating season, you should rinse the top with a hose to remove dirt as well. Is ice clogging the vent or pump? If so, you'll need professional help.
PILOT CONTROL ISSUES
Check the pilot light. Is it off? You need to try and re-ignite the pilot. Turn off the furnace and wait 15 minutes for all the gas to clear the lines. Once the gas is clear, turn the furnace back on and find the ignition switch. If the pilot won't light you'll need to check the gas line. If you smell gas, evacuate your home and call a professional right away.
