The thermostat instructs the heater on how to function. You set a temperature, the thermostat sends a signal, and the heater responds.
Of course, this also means that any issues with the thermostat could be causing the heater to malfunction. That issue could be anything from a programming error to a genuinely broken thermostat. The next time you believe that your heater is giving you problems, hold off on calling for furnace repair in Long Beach, CA.
The problem could simply be one of these thermostat issues:
Check the Settings
Before attempting to fix anything, check to make sure that the problem isn’t simply due to a programming error. If you visit the manufacturer’s website, you should typically be able to find a digital copy of the instruction manual for no charge.
That being said, here are some of the most common troubleshooting errors across all brands of digital thermostats:
- If you’re using a heat pump, make sure that it’s set to heating mode. As simple as it sounds, it’s easily forgotten.
- Check that the thermostat is set to “auto” instead of “fan mode.” Fan mode means that the blower fan will continually blow regardless if the furnace is generating heated air. That could explain why it feels like cold air is coming out of your vents.
- The “hold” setting is used to lock the temperature in place, in the event that you’re trying to use the thermostat outside of its normal programmed settings. Whether you’re forgetting to use the hold setting or if you’ve forgotten to undo it, it can cause some confusion in operating the thermostat.
Inspect the Thermostat
If everything is fine with the programming but you’re still having issues, it could be time to inspect the thermostat:
- Programmable thermostats use batteries to save schedules and perform other functions. Try replacing the batteries.
- The sensors may become inaccurate if they’ve collected dust or dirt. Gently wipe them off and see if performance improves.
- Perhaps your thermostat is tripping the circuit breaker for some reason. Check the circuit panel to find out.
- If none of the above helps, then you might have an issue with the wiring. We don’t suggest trying to fix this on your own, as working with electricity can always be dangerous.
Consider Replacement
When all of the above fails, it might be time for a replacement. Thermostats don’t need replacement often, but there are a few situations where it makes sense:
- If it’s been more than 10 years, or if your thermostat still uses a slide or dial instead of a digital display, it’s definitely time for a replacement.
- Have another HVAC contractor give you a second opinion on the location of your thermostat. If it’s too close to a warm area like the kitchen—or in a place that’s cold and doesn’t reflect the average temperature of the home—then it might not be recording temperatures accurately.
