Defrost Control Board Heat Pump
Defrost Control Board Heat Pump. I assume if the jumpers are on delay then the timer is used based on the second jumper and. So, for the y terminal at the heat pump defrost board, if a wire with purple sheathing leaves the y terminal at the indoor air handler, then the other end of that purple wire should be tied into the y terminal at the heat pump.
Test with a voltmeter set to “volts ac” to make sure the power is off. Turn off both high voltage and low voltage power by pulling the unit’s disconnect and turning the indoor air handler off. With a small footprint designed to be quickly installed in the tightest spaces, you’ll be on to the next job in no time.

Please know what your purchasing before hand. I cannot find anything that explains what the difference between no delay and delay are. During the defrost cycle, the heat pump is operated in reverse.
It Doesn’t Matter What Color That Wire Is.
How much is a defrost board for a heat pump? Guaranteed to work or your money back! First, the condenser fan motor is turned off during defrost, and second, the defrost control board energizes the ‘w’ terminal turning on the electric strip heat.
Replacing The Defrost Board Will Likely Cost About $350 To $400.
A defrost control tells the reversing valve when to send hot refrigerant outdoors to thaw the outdoor coil. Auxiliary heat lockout above the selected temperature, auxiliary heat will only run during defrost operation. If it didn't, cold air from the fan prevents the melting effect of the hot refrigerant.
Turn Off Both High Voltage And Low Voltage Power By Pulling The Unit’s Disconnect And Turning The Indoor Air Handler Off.
Your defrost control board is responsible for monitoring the heat pump’s operating conditions that are likely to form ice. The defrost cycle is activated by the defrost control, which detects ice building up on the evaporator coils and uses the reversing valve to briefly reverse the heating process to melt the ice on the coils. Honeywell’s universal heat pump defrost control helps keep the heat on during cold winter months.
Hello, I Cannot Find Any Information On My Heat Pump Defrost Control Board.
With a small footprint designed to be quickly installed in the tightest spaces, you’ll be on to the next job in no time. Because it has timers and some basic “logic,” the board requires a power supply, and for most residential split system boards, this power comes from the c (common) and r (hot) terminals from the indoor 24v transformer. The first thing to remember is that the heat pump operation in defrost is the same as when the system is cooling with 2 differences.
