Why Isn’t My Thermostat Working?
Between the heat and high humidity in Concord, NC, you understandably rely on your air conditioner to keep your home comfortable throughout the summer. When the thermostat is seemingly non-responsive, however, it makes sense to look for a quick-fix solution to common problems before you schedule a professional AC repair service.
The Batteries Are Dead
One of the most common reasons why a thermostat stops moderating control of the AC system is because the batteries are dead. Remove the mounted unit from the wall and see if the thermostat is hard-wired or uses batteries. If you see batteries, replace them before reaching for the phone to schedule repair service.
The Circuit Breaker is Tripped
If your manual adjustments to the thermostat fail to generate a response from the system, check your circuit breaker box to look for a tripped or blown fuse. You can easily replace a blown fuse or reset your circuit breaker to correct this common issue.
The Thermostat is Dirty or Corroded
Your thermostat must be able to communicate via its bimetallic coil and its contact surface as well as via connecting wires. With the wall-mounted unit in your hand, visually inspect the wires, bimetallic coil, and contact surface to determine if cleaning or minor repairs may be needed.
The Thermostat is Not Mounted Correctly
To function properly, the thermostat should be mounted 5 feet above the ground, and it must be completely level. Use a tape measure and a bubble level to confirm that the thermostat has been installed properly.
A Replacement Thermostat Should Be Installed
As is the case with all mechanical equipment, a thermostat will eventually reach the end of its useful life and will need to be replaced. A consultation with one of our HVAC repair technicians is an easy way to determine if the installation of a new programmable thermostat will resolve the problem.
