What to do if your thermostat goes out?

What do you do if your furnace goes out as waking up to a chilly is never pleasant? The following things to check seem like commons sense, but are actually overlooked a lot of the time, and are simple fixes you can DIY (do-it-yourself). First, check that the thermostat is set to “on” and “heat”. Then, check that your settings are all correct, and that the display is accurate to the date and time. It’s also a good idea to consider replacing your battery if you cannot recall the last time you had replaced it. If you see any dust or debris in the thermostat, you will want to blow that out. If all of the above has been done, and your thermostat still won’t kick on, check your wiring and make sure that there are no breaks in it.

Other things to consider are, checking that the gas line is turned on, checking that your chimney flue is clear from obstruction, make sure that your filter is clean as there is an auto shut-off on most machines if the filters are dirty and clogged. Finally, make sure that your drain hose is clean – you can take off your drain hose and run equal parts bleach and water down it to flush out and dirt or mold that may be present.

If nothing seems to work, you may need to purchase a new furnace.  In addition, here are some heating tips:

  • Check the circuit breaker and power supply: If the furnace stops working or the thermostat’s screen is blank, check if the circuit breaker tripped or blew a fuse. Also, make sure the power cord is plugged into an outlet.
  • Reduce drafts: If a draft causes problems with the pilot light, you may need to close the windows or doors in the room.
  • Maintenance: Every year, at the end of the summer or beginning of fall, hire a furnace repair specialist to inspect and maintain the furnace. The professional will get the unit ready for the upcoming cool weather and fix problems that could cause breakdowns or expensive repairs during busy winter months.
  • Furnace Installation: If you need to replace your furnace, use a furnace contractor’s expertise to determine the right type and size for your home or commercial space.
  • Ignition control or pilot light problems: As problems may result from clogged components or faulty electrical components, leave ignition issues to the experts.
  • Mechanical issues: Unless you received training to repair furnaces, let professionals handle problems related to mechanical wear and tear. Otherwise, you may void the warranty on the appliance or accidentally cause a larger problem.
  • Natural gas or propane problems: When you suspect problems with the gas feed or valve because of a malfunction with the gas pressure regulator, call a professional for help.

Never hesitate to contact an expert technician at Utah HVAC.  Any furnace, regardless of its age, may pose combustion- or gas-related safety hazards, so it’s always a good idea to have an expert examine the unit and suggest the best course of action.
