There is nothing more terrible than waking up cold in the middle of a bone-chilling night. It’s one thing if you need to pull the covers up, but it’s an entirely different problem if your furnace is working inefficiently or not working at all.
With a little do-it-yourself experience, you can troubleshoot and overhaul your furnace on your own. You must have a maintenance checklist for your heating unit to avoid the problem. Here are some common problems and easy solutions to those issues which you might face:
A Tripped Breaker
If your furnace is not working despite the switch being on, check if you have a tripped breaker. It would help if you labeled your breaker box “Furnace” or “HVAC” next to the correct breaker. If not, search for a tripped breaker and reset it, if you can. Be cautious. A tripped breaker and burnt fuse may suggest a greater issue with your electrical system that needs repair. It’s best to be on the safe side and have a certified electrician or HVAC expert inspect it.
A damaged thermostat can lead to several issues with the fan or comfort levels. If your furnace doesn’t produce any heat to warm up your residence, check the battery level in the thermostat. Simply replacing the battery might do the trick in some models.
Thermostat Batteries Low
If you have a battery-operated thermostat, the cells may be dead. Many programmable thermostats feature a flashing “low battery”. You should put in fresh batteries if you see a “low battery” warning near the control screen.
Is The Switch Working?
If the thermostat is working, see if the furnace power switch is put off by looking at the switch mounted on the side of the unit. It may be a simple light switch on the wall; some have a switch with a fuse. You should check to see if it’s darkened or burnt. If that’s the case, then you should replace it and turn the switch back on.
Vents And Registers Blocked
If your furnace cannot keep your house warm, You may block your outflow vents and registers. This is particularly common for heating ducts on the floor. You should see if your vents are open and that no carpets or furniture are impeding them. Vents are usually found near external walls under windows. Even long curtains can hinder airflow or redirect it to different other directions. If your vents are closed, plan a duct cleaning service to get everything smooth again.
Clogged-up air filters decrease airflow, making a furnace work harder to circulate the air. A blocked filter may damage the limit switch, which regulates the fan. It would help if you cleaned or replaced the filter once every month. A furnace repair expert can do this for you efficiently.
