What to Do When Your Rheem Thermostat Fails

Your thermostat plays a central role in your air conditioner’s performance. If it malfunctions, even a healthy AC system won’t function correctly. Recognizing the signs of thermostat failure can save you from unnecessary discomfort.

Key signs to watch for:

• No response to settings – If your AC doesn’t turn on or off when adjusted.
• Display errors or blank screens – Loss of power or internal faults.
• Short cycling or long cycles – Poor communication between thermostat and AC unit.
• Incorrect temperature readings – May cause overcooling or overheating.
• Delayed reactions – A slow response could indicate internal sensor issues.
