San Mateo HVAC – Programmable Thermostat Troubleshooting

San Francisco Bay Area homeowners often have programmable thermostats installed to enjoy energy savings and a more comfortable home. However, just like any other equipment, a programmable thermostat may malfunction, or even need to be replaced on occasion. If your programmable thermostat is on the blink and you believe the only solution is to replace it, try these tips first.

Check the condition of the fuse. In thermostats that are wired, it isn’t uncommon for a fuse to blow. Closely look at the filament inside the fuse to see if it may be broken. If the fuse is the issue, a replacement can be purchased at your local hardware store and installed in an instant.

If your programmable thermostat operates on batteries, it may be time for new ones. Programmable thermostats may work one of two ways – either on battery power, or wired. It’s a simple matter to determine whether the batteries may be the culprit for your thermostat not working. Just put new batteries in after turning the thermostat to the off setting, then switch it on to see if it works.

Verify proper installation. Even when professionals install your programmable thermostat, wires can become loose. This is even more common if the unit was not installed by a professional technician. Remove the cover and ensure that all wires are securely connected. Be sure if your thermostat is connected to your home’s electrical supply to turn the power off while you check for loose connections.

Is your HVAC system working properly? In some cases Bay Area homeowners suspect their programmable thermostat is on the blink when it is actually the HVAC system itself that’s the issue. For instance, if your air conditioning isn’t working in summer months, switch the unit to heat, adjust the thermostat up, and see if the system comes on. If it does work on the heat setting, it likely isn’t the thermostat, but your HVAC system that needs attention.

When you have tried all of the above and still cannot diagnose the problem, it may be time to consider a new programmable thermostat.
