Frigidaire Air Conditioner Buttons Not Working – Causes and Solutions

Frigidaire is one of the most popular and reliable air conditioner brands on the market. However, even the best appliances can start to develop issues after years of use. One common problem Frigidaire AC owners face is buttons on the control panel that stop working properly. This can prevent you from turning on the unit or changing fan speeds and temperature settings.

When your AC buttons become unresponsive, it’s incredibly frustrating, especially during the hot summer months. Before you call an HVAC technician, the good news is that many button issues can be fixed yourself with some simple troubleshooting. This comprehensive guide will walk you through the various causes of Frigidaire air conditioner buttons not working and provide solutions to get your unit back up and running.

Why Do the Buttons Stop Working on My Frigidaire AC?

Frigidaire air conditioners have electrical control boards and wiring that send voltage to components when you press the buttons on the control panel. Over time, normal wear and tear as well as damage can disrupt the electrical pathways that allow the buttons to activate the fan, cooling, and other features. Here are some of the most common reasons behind unresponsive buttons:

Software Glitches

Like any electronic device, AC units can periodically experience minor software problems. A glitch in the programming can cause the buttons on the control panel to temporarily freeze up and stop responding when pressed. Just like restarting a computer, resetting your Frigidaire unit can often clear up a software hitch.

Loose or Disconnected Wiring

The constant vibration from the motor and fan as well as moisture and corrosion over many cooling seasons can loosen wiring connections inside the control panel. If the wires become too loose or disconnect entirely, electrical signals can’t travel from the buttons to the components they control.

Faulty Control Board

The control board is essentially the brain of the AC, telling the fan, compressor, and other parts what to do when you press buttons. If the control board malfunctions or fails, the signals can’t get through and the buttons will become completely unresponsive.

Tripped Circuit Breaker

Air conditioners pull a lot of power, especially window units on shared circuits. If too many appliances overload the circuit, it can trip the breaker. This cuts off electricity to the outlet powering the AC. With no power, the buttons will be dead until you locate and reset the tripped breaker.

Broken Fan

When an AC’s fan motor fails, the fan won’t spin to blow air across the evaporator coil to produce cold air. If the fan is broken, the unit won’t properly cool the room no matter what buttons you press. This can make it seem like the buttons aren’t working correctly.

Refrigerant Leak

The refrigerant is the substance that allows the AC to produce cold air. If there is a leak and the refrigerant level drops too low, it prevents proper cooling even if the unit is turned on. Buttons may appear unresponsive if the cooling system isn’t functioning due to low refrigerant.

Now that you understand why Frigidaire AC buttons commonly stop working, let’s go over some steps for diagnosing and repairing the issue yourself.

Troubleshooting Unresponsive Frigidaire AC Buttons

When your Frigidaire air conditioner buttons go unresponsive, there are several troubleshooting steps you can take before calling for professional service. Here are some tips to help diagnose and fix the problem:

Reset the AC

As mentioned earlier, software glitches can sometimes cause the buttons to freeze up. Reset the Frigidaire unit by turning it off or unplugging it for 5 minutes. This reboot often clears up a minor programming hiccup. Plug it back in and try the buttons again. If they start working, a simple reset fixed the issue.

Check for Loose Wiring

Open the front panel of the AC unit to access the internal control board and wiring. Visually inspect all the wires and electrical connections. Check for any wires that have come loose from their terminals. Push any loose wires back into place and tighten the screws on the terminal. Test the buttons again once all wires are securely reattached.

Test the Control Board

Use a multimeter to check for electrical continuity in the control board circuits. This can identify if the circuits have failed causing the buttons to be unresponsive. If the control board tests faulty, you’ll need to replace it. Search the model number to find the correct replacement control board for your Frigidaire model.

Inspect the Circuit Breaker

Check your electrical panel and locate the circuit breaker controlling the AC unit. Flip it all the way off and then back on again to reset it. This may be all that’s needed if the breaker tripped from an overload. If it trips again instantly, you’ll need to reduce the number of appliances running on that circuit. Dedicate it to the AC alone if possible.

Examine the Fan

Open the front grille of the AC unit and check the condition of the fan. If the motor doesn’t run or the fan blades are damaged, it will need to be replaced. Check the user manual for how to remove and install a new fan motor and blade assembly. Proper air flow is required for the AC to produce cool air.

Check for Refrigerant Leaks

If you’ve ruled out the other issues, low refrigerant is likely preventing the AC from cooling properly. Signs include warm air coming from the unit even when on and ice buildup on the refrigerant lines. Unfortunately refilling the refrigerant requires special equipment and professional service. Schedule an appointment with an HVAC company to inspect for leaks and recharge the AC’s refrigerant if needed.

When to Call an AC Repair Technician

While many common AC button issues can be addressed with simple DIY repairs, there are certain situations where it’s best to rely on a trained HVAC technician:

Refrigerant Recharge

If your AC isn’t cooling properly due to low refrigerant levels, do not attempt to recharge it yourself. Handling refrigerants requires certified training and special equipment to do legally and safely. An expert can pinpoint the leak, repair it, vacuum out the lines, and properly recharge the system.

Component Replacement

Complex parts like the circuit board, evaporator coil, compressor, and fan motor should be replaced by a professional. They have the technical know-how to remove and install these components correctly. Improper repairs can damage your AC.

Electrical Issues

Unless you have electrical training, it’s not advisable to work on the wiring yourself. An experienced technician can use testing equipment to diagnose electrical faults you may miss through basic troubleshooting. They can fix wiring safely.

Advanced Diagnostics

If you’ve tried all the DIY troubleshooting tips with no success, a technician has specialized tools and know-how to get to the bottom of the problem. Advanced diagnostics can identify issues you can’t detect, saving you frustration and money.

While the cost of professional HVAC service may seem high, complex repairs done incorrectly can end up costing you more in the long run. For anything beyond minor troubleshooting, don’t hesitate to call in an expert to get your AC functioning properly again.

Preventing Future AC Button Problems

To help avoid headaches from air conditioner buttons failing in the future, there are some simple maintenance practices you can follow:

Change Filters Regularly

Clogged, dirty filters make your AC work much harder to push air through. This extra strain can lead to fan motor failure and put excess stress on components. Change disposable filters each month or wash reusable ones to keep air flow obstruction minimal.

Clean the Condenser Coil

The condenser coil on the outside of the unit can accumulate dust, dirt, and debris easily. This coating severely reduces its heat-transfer abilities. Use a hose and brush to gently clean the coil of built-up gunk once a year.

Check Refrigerant Levels Annually

Have an HVAC technician inspect the refrigerant level each year before cooling season starts. Top it off if low to prevent leaks. Proactively maintaining proper charge reduces strain on the compressor and evaporator.

Tighten Connections

Vibration from the motor and fan can slowly loosen electrical connections over time. Check wires and terminals each year and tighten any that seem loose. This prevents wires from disconnecting and interrupting power to components.

Use a Surge Protector

A power surge when the compressor cycles on and off can damage the control board. Plug the AC into a surge protector to regulate voltage spikes that can disrupt the unit’s electronics.
