Reversing Valve
The reversing valve switches between heating and cooling modes. A stuck valve leaves you stuck in one mode.
Heat Pump Accumulator
The accumulator prevents liquid refrigerant from reaching the compressor. A failed accumulator can lead to compressor damage.
Crankcase Heater
The crankcase heater keeps compressor oil warm to prevent refrigerant migration. A failed heater leads to hard starting and potential compressor damage in cold weather.
Auxiliary Heat Relay
The auxiliary heat relay controls electric heat strips for backup heating. A failed relay leaves you without supplemental heat during extreme cold weather.
Electric Heat Strip
Electric heat strips provide backup heating inside the air handler. A burned-out heat strip reduces heating capacity when you need it most.
Freeze Stat / Low Ambient Control
The freeze stat prevents indoor coil freezing during low-temperature operation. A failed sensor allows coil freeze-up and potential water damage from ice melt.
