6 Reasons Why Window AC Control Panel Not Working – Let’s Fix It

Don’t worry you’re not the only one who’s dealing with Window AC Control Panel Not Working problem. There are many people who are facing the same issue. The problem is the window air conditioner cooling gets off without any reason. Sometimes it shows error and sometimes it does not cool at all.

When you notice that your air conditioner’s control panel isn’t working properly, the first thing you should do is try to fix the problem yourself. Instead of calling an expensive HVAC technician, try our guide to troubleshooting common issues with an AC control panel that are easy to fix on your own.

When your Windows air conditioner stops working, it is likely due to one of two different issues: the control board or the PCB.

Troubleshooting and replacement are the only way to determine which component needs to be fixed. If you run into issues with your unit, don’t hesitate to call a professional.

Window AC Control Panel Not Working – Troubleshoot And Diagnosis

When they aren’t treating you to the coolest air of your life, the best window air conditioners are putting in work 24/7. You might not see them, but they’re hard at work, cooling off rooms and making customers happy. But every once in a while, an air conditioner button can get stuck and become unusable.

Window AC Control Panel Not Working

1. Reset the Unit

The best way to repair your faulty AC is by resetting it.

Resetting your unit will clear some of the system glitches that might be causing the manual controls to act up — like buttons becoming unresponsive.

If your AC is not cooling off, even when the temperature setting is properly adjusted, it’s possible that the issue is being caused by a glitch in the software. If you don’t know how to reset your AC, then consult your owner’s manual.

2. Check Control Board

The control board of your air conditioner is the brain of the entire unit. It controls everything from the roller to the fan motor. If your unit’s control board malfunctions and stops working, then none of the other functions will work either. You may locate the control board by looking for a circuit board inside your AC unit. First, unplug your AC from the power outlet and set it aside.

The first step would be to test out the controls with multimeter or voltmeter. If there is no continuity, then your whole unit is probably malfunctioning and you will need to replace your whole system instead of repairing it.

3. Defective Circuit Board

On the other hand, when your air conditioner’s circuit board stops working, it can prevent all manner of parts from providing power. This means that you may lose the ability to regulate voltage, which will harm more components.

Replacing a bad circuit board is quite complex, and even experienced technicians have difficulty doing so without accidentally damaging other parts. If your air conditioner’s circuit board has gone bad, get in touch with a professional as soon as possible.

4. Electrical Problem

Don’t worry if the AC stopped working suddenly. First, you must check whether it is plugged in. Lots of people forget to plug their air conditioner in, which can make the room uncomfortably hot. Next, you must locate the circuit breaker box. It will be located near the main electrical panel and it has a red cover.

Find the correct circuit breaker and reset it. If that doesn’t work, you should replace the fuse. After that, you should unplug the unit and clean the contacts in the plug.

If a fuse blows when you are trying to operate a fan, it is probably due to a short circuit inside the fan. You should turn off the breaker and carefully check if there is any visible damage. You should also clean the contacts.

In order to ensure your window unit works properly, inspect the connection every time you use it. If a problem becomes apparent, you should consult a professional to resolve the issue.

5. Breaker Keeps Tripping

Your air conditioner is tripping the breaker, but that’s not necessarily a sign of a problem. You could just have too many things running off of the same outlet or circuit, which would explain why the air conditioner is malfunctioning.

If you have other appliances on that circuit, they’ll stop working, too. Keep the air-conditioner on a dedicated circuit to avoid this problem.

To keep your window air conditioner from overheating, use a 15-amp dedicated circuit to power it. This will avoid the circuit breaker from shutting down and it will also prevent other appliances on the outlet or breaker from overloading.

6. Broken Fan

The mechanics of your AC unit are a little more difficult to comprehend. A fan within the unit pulls in hot air from your room, runs it over evaporator coils to take the heat away, and then pumps it back into the room as cool air. If the unit’s fan malfunctions or breaks, it won’t be able to distribute air — possibly causing your system to turn on even though nothing seems to be working.

While the unit comes with a built-in fan, it is recommended that you replace it once every two years. If your fan is broken, you should be able to find a replacement and install it in less than 30 minutes by following the instruction manual.

7. Malfunctioning Or Broken Temperature Control

When you have a problem with the temperature control, the first thing to check is whether the thermostat itself is damaged or unresponsive. This can happen over time, as the buttons on the unit are used countless times.

The buttons on the front of it tend to wear down after a lot of use — resulting in an inability to control the temperature of the room at any given time.

Don’t be afraid to call in a repairman and have him or her take care of the problem. The Window Air Conditioner temperature control can be tricky to replace, so if you’re not sure how to do it yourself, a professional should be called in.

8. Burnt Out Evaporator Coils

In an air conditioner, the evaporator coil plays an integral role in the cooling process. Because it is responsible for releasing heat from the air into your home, it can also become clogged over time, which can lead to lower efficiency and high energy costs. But a clean evaporator coil can go a long way towards saving on your monthly cooling bill.

When the window air conditioner’s evaporator coil is working incorrectly, the fan won’t cool your home. One sign that the evaporator coil is bad: If you push buttons on the control panel, but no cold air comes out of the vents.

AC problems can seem like a lot of work, but it is worth the effort to troubleshoot them. The first thing to check is the AC’s control board — if that does not work, you will definitely have another issue like the evaporator coil.

GE Air Conditioner Control Panel Not Working

The GE Window AC will occasionally experience an unresponsive touch panel. The issue occurs primarily when the ambient temperature is either very hot or very cold. As mentioned above, this is a temporary condition and should correct itself after several moments (up to a few minutes).

Haier Air Conditioner Control Panel Not Working

The air conditioning control panel is located somewhere in your home, probably inside the house. There are 4 wires coming out of the back of it. The most common reason for your air conditioning unit not turning on is a tripped thermal fuse or a circuit breaker.

If you own a Haier air conditioner controlled with a remote control, there’s a chance it could be broken and not functioning properly. The remote can become unresponsive due to damage that can occur in the course of normal use. This may prevent you from setting the temperature or changing fan speeds.

If you’re having trouble with your window ac unit’s control panel, there are a few things you can do to rectify the problem. First and foremost, you should check the electrical outlet and make sure that it’s working. If it is, then you might want to invest in a remote control for your unit. This can be used to control power settings as well as turn the unit on and off.
