Fix Frigidaire Air Conditioner Control Panel Not Working – Frigidaire air conditioners’ buttons frequently freeze due to software hitch or become non-responsive due to loose wiring, a defective user interface board, a tripped breaker, or a wrecked fan. Others fail due to a faulty thermostat or evaporator coil or a dead internal component.
Therefore, while the first five reasons are the most distinctive explanations, you cannot overlook the others and again, it simply depends on the type of buttons that are non-responsive.
Frigidaire Air Conditioner Control Panel Not Working – Fix It
The motives for a failing control panel button might differ from those of the power button or the remote-control buttons and to help you understand that, we’ll discuss them later separately.
Furthermore, we’ll take you through the AC reset methods and steps to allow you to quickly fix some of the issues and get the buttons working again.
Why is Your Frigidaire Air Conditioner Control Panel Not Working?
The AC type notwithstanding, your Frigidaire air conditioner buttons are not functioning due to one of these reasons:
-
Software Hitch – Which Freezes the Buttons
Now, since Frigidaire air conditioners are software-driven, a hitch could have happened, freezing up the buttons. Frozen buttons are usually non-responsive.
Fix
Now, while there is no way to check for a software-driven hitch, you can simply fix the issue by resetting the air conditioner. One way to do it is by turning it off for at least 5 minutes to reset the unit’s controls.
If that doesn’t work, the issue wasn’t a software glitch. Therefore, you need to consider the other reasons shared below.
-
Loose Wiring Inside the Unit’s Control Panel
Now, any loose wires in the AC’s control panel might cut off communication between the control panel and the buttons. Therefore, the buttons will become non-responsive when you simply press them.
Fix
Now, to ensure you are having a wiring problem, you need to press down the non-responsive buttons with one hand and the control panel with the other. If the buttons reply, then the issue is loose wiring which you should fix. Rather, call a service technician for help.
-
Faulty User Interface Board (Within Your Control Panel)
The control panel comes into play again here. If its user-interface control board malfunctions or stops working, the AC’s buttons develop non-responsive.
Now, remember, this board (the user interface board) houses the buttons and processes the temperature settings you pick. Therefore, it’s a dangerous element in running your AC and the performance of the control panel.
Fix
You’ll have to substitute the user interface board if it is faulty. While there are numerous cooperative tutorials on YouTube, getting an expert opinion first is important as the cause could be something different.
-
Tripped Breaker
We probably should have mentioned this first, as it’s the coolest to check. Though, since it’s not as common as the first three, we’ll discuss it here.
Mainly, a circuit breaker is likely to trip due to a circuit overload. Doing so defends your air conditioner from potential electric damage, which is a good thing.
The downside is that your AC’s buttons, particularly the power button, fail to work.
Fix
You need to check the circuit breaker to ensure it’s not tripped off. If it is, reset it. But if the problem occurs repeatedly, it’s time to call a technician.
-
Broken Fan
The fan is vigorous in driving warm air over the AC’s evaporator coils for cooling. Once it breaks, it’s unable to do that, which means your AC won’t fill with cold air.
The bouncing effect is that your AC won’t run when you press the buttons. Therefore, you might assume that the controls are defective when they aren’t.
Fix
You simply need to disconnect your Frigidaire air conditioner from the power and locate the AC’s fan with the support of the unit’s manual. Then, just inspect the fan. If it’s broken, replace it.
-
Malfunctioning Thermostat
The temperature control, then known as the thermostat, is likely to fail the AC’s controls if it malfunctions. Generally, a faulty thermostat causes temperature problems such as non-uniform heating and cooling and irregular sequences.
Fix
If the thermostat has a problem and doesn’t work, you need to replace it. Simply using a multimeter, you can test your AC’s thermostat for continuity. Looking for continuousness means the thermostat is faulty.
-
Faulty Evaporator Coil
The evaporator coil’s work is to take out heat from the unit’s cabin and shorten it to promote cooling. If you simply press the AC’s buttons and no cooling takes place, then it’s probable that one key player, which could be the evaporator coil, is faulty.
Of course, the same could occur if the control board (discussed next) is wicked.
Fix
A faulty evaporator coil needs a replacement. This fix is, though, best left to HVAC technicians.
-
Dead Internal Component
Now, if none of the above seven problems is wrong with your air conditioner and the buttons will still not work, it’s extremely likely that one of the internal parts is defective.
Now, in particular, you simply should check the circuit board (or PCP) or the main control board. One of them could be defective, and it occasionally means changing both boards.
Then, for one, the circuit board supplies the AC’s socketed parts with power under the grasp of the control panel. If it’s defective, it’s unable to turn on, which simply means the buttons will be non-responsive.
Meanwhile, the control board holds everything together. It is your AC’s brain, and everything works through it, including the control panel. Therefore, if you just press the control board and nothing works, the odds are that you have a dead control board.
Fix
You need to have an expert examine the PCB and main control board for fault. You’ll simply need to replace them if they are dead or get a new AC.
The latter is a choice because the cost of replacing the main control together with the PCB is near that of getting a new air conditioner.
