Tips to Know if Your Thermostat is Working ProperlyIf you’re suddenly having problems maintaining the desired temperature level inside your home, then it’s more than likely that something has gone wrong with your power supply, or your HVAC system.  First check the circuit breaker and fuses, and then test whether other home appliances are working properly. If all is fine in this area, then it’s time to inspect your HVAC or whatever type of home heating and cooling equipment you have.  However, don’t assume the worst – it may only be the thermostat playing up.

Checking the Thermostat

Whether this is an easy process or not, depends upon the age of your system and type of temperature regulator. Make sure you’ve got the manufacturer’s technical manual on hand before you start tinkering with the system.

  • Old electromechanical devices may have bimetallic strips, switches and coils, residing under a cover
    • Check for dirt, loose wires or corrosion that may indicate a problem

  • In comparison, digital, electronic models (including WiFi devices)  are a breeze to check
    • The panel being unlit, unresponsive to touch controls, or with an error code is a good indicator of part failure.

Thermostat Repairs

Before proceeding to fix any issues, consult your warranty. If you’re covered, get your HVAC contractor out to fix the problem. If you’re out of warranty, and are comfortable with attempting to fix any identified problems, then proceed with caution:

  • Try removing dirt and other substance build-up with a brush, being careful not to damage any parts
  • Use compressed air to blow out gunk from hard to reach places
  • Repair loose screws and wiring

Thermostats are relatively cheap parts to replace, so if you can’t fix the problem, get a qualified technician in to inspect and quote for repair or replacement, and to see if the problem is bigger than a faulty thermostat.
