Frigidaire makes some of the best air conditioners on the market, but that doesn’t mean that the buttons will always work. This can occur when the PC board or control board is malfunctioning and requires a quick fix. Follow along as we explore how you can diagnose and fix a Frigidaire air conditioner when the buttons aren’t working.

Frigidaire is one of the leading manufacturers of air conditioning units on the market today. Their line of air conditions is one of the more trusted and popular lines out there. Simply put, they make a quality product more often than not.

There are times, however, where one of their window air conditioning units may not work correctly. One problem, in particular, will see the unit’s buttons stop responding.

When the buttons on your Frigidaire air conditioner stops working, this is most likely due to either the control board or the PC board. Troubleshooting the issue is the only way to way to determine exactly what needs to be fixed. However, don’t refuse to call a professional if you can’t find the problem.

Buttons Not Working On Frigidaire Air Conditioner

The two most common issues when the buttons on your Frigidaire air conditioner don’t work are malfunctions with the control board and the circuit board.

When one of these components stops working, you may not be able to perform a fix on your own. It all depends on your level of handiness as well as your experience with air conditioner components.

Control Board

The control board does just that: it controls all of the functions within the air conditioner. When the control board malfunctions or stops working altogether, then the buttons will not respond when they are pressed.

If you are familiar with electronics to some degree, you may locate the control board. Using a multimeter, you can test the control board for continuity. If there is none, then you will have to replace the control board entirely.

Circuit Board

Likewise, the circuit board, also known as a PCB, is the base that physically supports the socketed and surface-mounted parts within the air conditioner. When the circuit board goes bad, the components may not get the necessary voltage to power them.

Replacing the circuit board is complex, and it is not recommended that you do it yourself. A professional can best assess whether or not the circuit board is at fault and replace it without potentially doing further damage to any other components.

What Are Common Air Conditioner Button Problems?

While the most common issues with non-working buttons lay in the control board, that said, they are not the only issues that can keep the buttons from working. If one of the other components is not responding, then the buttons will seemingly not work.

There are several secondary problems that could be at hand, so you will have to do some troubleshooting to determine the issue.

Electrical Issues

Aside from issues with the control board, the most common problem facing window air conditioners is the electrical connectivity. That means either the unit is not plugged in or there is no power going to the outlet where the unit is plugged.

First and foremost, make sure the unit is plugged in. It kind of goes without saying that the buttons won’t work if there is no power going to the unit at all.

If the unit is plugged in, check the circuit breaker next. From time to time, the breaker that the circuit is on will trip due to a surge.

The breaker acts as a security measure to prevent those surges or potential fire hazards from happening. Simply go to your breaker box and flip the breaker back into the”O” position.

The Breaker Repeatedly Trips

Speaking of electrical issues, there is a chance that whenever you run the air conditioner, the breaker trips. The most likely explanation for the breaker constantly tripping is that the air conditioner is overloading that circuit.

Generally speaking, most window air conditioning units are designed to use the standard 120-volt, 15-amp circuit. If you have other appliances running off of that outlet or breaker, the circuit could have an overload and shutdown.

Keep your window air conditioning unit on a dedicated circuit. That way, you will keep your circuit from becoming overloaded and the air conditioner from shutting down.

The Fan Is Broken

The way your air conditioner works are pretty simple. A fan within the unit draws in the warm air from your room, runs it over evaporator coils that cool it down, and then passes them back into the room as cold air.

When the fan inside your unit malfunctions or breaks, the unit has no way of distributing air, so when you press the button to start the machine up, it may seem like the buttons don’t work when the fan is the issue.

The fan is relatively easy to access; check your user manual to find its exact positioning. Remove the old, broken fan and replace it with a new one.

Malfunctioning Or Broken Temperature Control

Of the buttons on the front of the unit, temperature control is the most commonly used. After all, these are the buttons that you would press to dictate the temperature within the room at a given time.

When the temperature control has become damaged, worn, or unresponsive, then pressing the button won’t do a whole lot.

Because there are other potential issues at play, you will likely have to do some troubleshooting before coming to this conclusion. The temperature control can be tricky to replace, so don’t be afraid to call in a professional to do the job.

Evaporator Coils Burned Out

As you can see, it is tricky determining when the buttons are not working, and another component is at fault. It usually takes a little bit of time and troubleshooting to come to that determination. When it comes to the cooling system, the evaporator coil plays an integral role in the cooling process.

When the evaporator coil is not working correctly, the fan pushes warm air through the system without cooling it.

One of the telltale signs that the evaporator coil is bad is if you push buttons on the control board, but there is no cooling action.

Always test out the control board first; it typically does not work at all when it is faulty. But if pressing the buttons does not get the cooling to start (and other functions work), you can anticipate another issue like the evaporator coil.

How do I know if my AC fuse is blown?
Run the same test on the”loa” side of the fuses if you saw a voltage reading during the previous step. A reading of 220 to 240 should be seen once more. You have a blown fuse if you observe a voltage reading on the”lin” side but not the” loa” side.
How do I remove the control panel from Window AC?
Remove the screws from the control panel’s sides and bottom. Raise the control panel above the air conditioner and keep it there.
Unplug the user interface control board’s wire harness connection. Place the control panel on a padded work surface, facing down.
What causes the outside AC unit to stop working?

Fan failure, electrical issues, frozen coils, and refrigerant line issues are some of the other problems that might cause your outdoor unit to cease working. A certified technician will need to check into these difficulties.
