Problem With That Programmable Thermostat? Consult This Checklist Before You Buy Another

Problem With That Programmable Thermostat? Consult This Checklist Before You Buy AnotherProgrammable thermostats are a great way to save energy and money in your San Antonio home. But what about when your programmable thermostat seems to go on the fritz? You may automatically think you need to replace the thermostat, but this is not always the case. Consult our troubleshooting checklist before you replace your thermostat.

  1. Check the Batteries. This may seem like an obvious step, but many times if your thermostat is not working properly it is because the batteries are low. Purchase high performance batteries for your thermostat and replace them according to manufacturer’s instructions. If the thermostat still doesn’t seem to be functioning correctly even with new batteries, move on to step two.
  2. Check the Fuse.  Most programmable thermostats have a fuse inside of them. Use your owner’s manual to locate the fuse, and if the filaments appear to be separated then take the fuse to a home improvement or hardware store to purchase a replacement. If the fuse is fine, or you have replaced it and the thermostat is still not working properly, move on to step three.
  3. Try the Other System. If the thermostat won’t turn on the A/C, then try your furnace. Adjust the temperature in such a way as to cause the furnace to kick on. If the thermostat won’t turn on one unit, but will control the other, contact an HVAC professional to asses the system that won’t turn on, as it is likely the culprit, not the thermostat.
  4. Replace the Programmable Thermostat. If neither system will turn on, it is likely that your thermostat needs to be replaced. Check to see if your thermostat has a recall or warranty, and if so follow instructions for a replacement. If there is no recall or warranty, purchase a new programmable thermostat and install it according to enclosed instructions.
