Reversing Valve
Component_Status: Stuck
"The heat pump wouldn't switch to heat during the coldest night. These guys diagnosed the reversing valve and had it fixed by morning."
Diagnostic Matrix.
Stuck in Cool
When the reversing valve solenoid fails or the internal slide gets stuck, your heat pump remains in cooling mode regardless of the thermostat setting.
Defrost Board
A faulty defrost board can cause your outdoor unit to freeze over, preventing the heat pump from extracting heat from the air effectively.
Logic Errors
Intermittent switching or strange noises often indicate a failing solenoid coil or communication errors between the board and the valve.
