A client in Altadena, CA, called us on short notice to fix a problematic central air conditioning unit. We offer same-day service — so we had the technician dispatched immediately to fix the issue before it got any worse. We quickly diagnosed the problem: a malfunctioning analog thermostat. The analog thermostat came when they first built their house, and it was high time to replace it with a new one. So we offered the client budget-friendly options, and they chose Honeywell’s non-programmable thermostat. Because this product worked with their existing wiring, we could install it at once. Then, before leaving, our expert gave it a final test to ensure everything was functioning properly.
There is a device known as a ‘thermostat’ on your heating and cooling system. It is in charge of the system’s brain function. You cannot see it or interact with it all the time, but that thing makes sure your heater or air conditioner functions smoothly. However, when something goes wrong with your thermostat, you will feel its effects sooner than later. And we know totally how frustrating that can be! In reality, many of our clients have experienced it too. Do you know how to identify if your thermostat has gone bad and what measures to take to fix it?
One of the first few signs that something is wrong with a thermostat is when the display goes dark. A blank screen could mean something is wrong with the thermostat itself — maybe all of its parts are broken or faulty — or it could be as simple as low batteries. Replace the batteries if necessary. If you have a hardwired connection, go to the circuit breaker and ensure that the breaker is turned on. Try resetting it, in case it has been turned off accidentally.
Your furnace or air conditioner may not turn on properly due to a malfunctioning thermostat. The electrical wires usually send signals from the thermostat to the HVAC unit — when to turn it on and what temperature to keep the house at. However, faulty wires can cut off communication between the thermostat and AC/furnace, rendering them useless.
HVAC systems are designed to run for a set period and then shut off for a set period. However, sometimes a faulty thermostat can cause the system to run non-stop. In this case, you can try flipping the switch from “on” to “off.” Unfortunately, a thermostat with bad wiring or is not calibrated correctly will continue to run even when in the “off” position.
Setting the temperature on your thermostat should result in an immediate response. You may hear a clicking sound followed by air movement through the ductwork. Placing your hand on a vent can help you feel for hot or cold air. You should feel or hear a difference within a minute or two of making changes. Otherwise, the thermostat may need to be replaced.
Programmable thermostats are designed to remember your settings and schedule over an extended period. If the thermostat suddenly starts forgetting your schedule, it may be time for a replacement.
