GMC air conditioner has no reset button in the body, control panel, or remote. You will find the on/off button, swing button, speed button, timer button, sleep button, fan button, heat button, cool button, and dry button. But there is no button called the ‘RESET’ button anywhere.
This applies to all GMC air conditioners, including inverters and mini, portable, or wall air conditioners. But that does not mean you cannot reset the AC if necessary.
Sometimes, resetting the GMC air conditioner can remove error codes or minor problems. However, make sure you identify the underlying problem and solve it permanently.
Then, How to reset the GMC air conditioner without the reset button
To reset the GMC air conditioner without the reset button, follow the steps below.
Apologies for the oversight. Let me provide the steps with subheadings for clarity:
Step 1: Power Off the Air Conditioner
Ensure the air conditioner is powered off by turning off the circuit breaker or unplugging the unit from its power source.
Step 2: Locate the Outdoor Disconnect Switch
Find the disconnect switch near the outdoor unit, typically housed in a metal box mounted on the wall or positioned nearby.
Step 3: Turn Off the Disconnect Switch
Open the disconnect box cover and flip the switch inside to the “Off” position to cut off power to the outdoor unit.
Step 4: Access the Indoor Unit
Return indoors to access the air handler or indoor unit, usually located in a utility closet, attic, or basement.
Step 5: Locate the Circuit Breaker Panel
Identify the circuit breaker panel that controls the indoor unit to ensure the power is completely cut off from the indoor components.
Step 6: Switch Off the Circuit Breaker
Turn off the circuit breaker corresponding to the air conditioner’s indoor unit to disconnect power effectively.
Step 7: Wait for the Reset
Wait for approximately five to ten minutes to allow the system to reset and discharge any residual power stored in its components.
Step 8: Inspect and Clean Air Filters
While waiting, inspect the air filters and replace or clean them as necessary to maintain optimal airflow.
Step 9: Restore Power to the Indoor Unit
After the waiting period, restore power to the indoor unit by flipping the circuit breaker back to the “On” position.
Step 10: Turn On the Outdoor Disconnect Switch
Return to the outdoor disconnect switch and flip it back to the “On” position to re-energize the outdoor condenser unit.
Bonus Step 11: Test the Air Conditioner
Set the desired temperature on the thermostat and test the air conditioner to verify that it is cooling effectively.
These step-by-step instructions ensure a systematic approach to resetting a GMC air conditioner without a physical reset button. Resetting the GMC air conditioner is easy, like a cup of tea.
