What is an air conditioner board?
This an authentic OEM display board for your room air conditioner. It is designed to display the selections the user has made for the air conditioner such as operating mode and fan speed. This is an escutcheon, otherwise known as a control panel overlay, for your air conditioner.
How much does an AC circuit board cost?
AC Circuit Board Replacement Price Replacing an AC circuit board costs $125 to $625. For parts, the AC circuit board ranges from $100 to $150.
Where is my AC control board?
The HVAC control board is where the thermostat wires connect to your heating and cooling system. In most cases the control board can be found at your furnace or air handler.
How much does it cost to replace an AC circuit board?
AC Circuit Board Replacement Price Replacing an AC circuit board costs $125 to $625. For parts, the AC circuit board ranges from $100 to $150. The circuit board sends power where it’s needed—it’s the brains of the outfit, and usually fails with age. It usually takes about an hour to repair.
How long does an air conditioner capacitor last?
approximately 20 years
Most are designed to last approximately 20 years, but a number of factors can cause them to wear out more quickly. If your air conditioner cycles much more rapidly than average, your capacitor is undersized (as mentioned above) or it’s built from problematic parts, and the estimated life span may be greatly reduced.
How does an air conditioner circuit board work?
A circuit board in the most common system works off of input and output. First, make sure you have power to the board. In some cases, this will be line voltage and other cases the board will get its power from the control transformer. Either way, check to make sure you have the proper input voltage to the board.
What are the little black cubes on an air conditioner circuit board?
In some cases, manufacturers make the board connections/terminations idiot-proof by using one-way Molex connectors/plugs. The little black cubes you see on the air conditioner circuit board are typical relays that will energize a fan motor such as a blower motor or a condenser fan motor.
When do you need to replace the AC circuit board?
Sometimes the relay contacts inside the little black cube will stick, and with a little tap, they release and close (or open if the fan motor will not stop when not calling for operation). In that case, you need to replace the air conditioner circuit board.
What causes an AC unit to bypass the circuit board?
Weak Blower Motor – Sometimes the blower motor fails. When it fails, the fuse blows, and the AC unit draws too much power. This high power causes a short circuit and burns out the circuit board. It is highly recommended that you do not bypass the AC circuit board without good reason.
