No need to brave the bitter cold. Look out for these signs and symptoms of a problem with your defrost control board to prevent cold toes and a sniffly nose.
The Unit Is Not Defrosting
Is your heat pump sporting some frosty fashion (aka ice) on the surface? Frequent and dense ice build-up on your outdoor unit is a sign you might have a problem with your defrost control board and sensors.
Outdoor Unit Runs Constantly
Your outdoor unit shouldn’t be running a never-ending race. If your outdoor unit is running non-stop, it’s likely struggling to absorb the heat from your home or release heat outside. It just doesn’t know when to call it a day! The inability to absorb and release heat can be due to a broken defrost control board and sensors, incorrect refrigerant charge, or an aging system that is no longer efficient.
House Doesn’t Reach Set Point
Experiencing inconsistent temperatures in your home? Your unit may be having trouble heating due to a faulty defrost control board and sensors. When your home isn’t reaching set point or your auxiliary heat is on frequently, it often points to a malfunction of these parts.
Did some of these signs and symptoms sound familiar? It’s time to break the ice and call your HVAC contractor to get down to the bottom of your chilly problem.
