Diagnosis and repair of heat pump defrost system faults — stuck defrost boards, failed sensors, and ice-damaged components restored 24/7.
We force the defrost cycle and test every component — board, sensor, relay, and thermostat — to find the root cause.
We safely remove heavy ice from the outdoor coil if the defrost cycle has been off long enough to cause accumulation.
Failed defrost boards, sensors, or thermostats are replaced with manufacturer-grade parts.
We confirm the defrost cycle engages and terminates correctly and there is no remaining ice hazard.
Common causes include a failed defrost control board, a broken ambient or coil sensor, or a stuck defrost thermostat. We pinpoint the exact fault with diagnostic testing.
Not safely — a defrost failure can lead to severe ice buildup, fan damage, or coil damage. We recommend turning the system off and calling for service.
Very — a stuck defrost can ruin the outdoor coil and compressor within days. Same-day repair prevents costly secondary damage.
