Turn unit off for a couple minutes. Then turn to cool for one minute. Turn unit off for a couple minutes. Then turn back to heat. You have successfully performed a defrost manually. If the unit continues to freeze up have a certified Technician check your defrost timer. It may need to be replaced. $120.00- $200.00 We discovered that the coils are used more if your heater is programmed to use them when you choose to turn up the heat more than 3 or 4 degrees at a time. Check the programming to see what your range is.

When an electric heat pump coil freezes in cold weather, you can first try increasing the temperature setting on the thermostat to help thaw the coil. If that doesn't work, you may need to manually defrost the coil by turning off the unit and using a hairdryer on a low setting to melt the ice. It's also important to check for any blocked vents or filters that may be causing the coil to freeze.
