AC Not Turning On but Not Humming: What to Do
When your AC is not turning on but not humming, the first step is to determine why. This can be the result of a variety of different problems, so it’s important to do a thorough diagnosis. In this article, we’ll look at some of the most common causes and how to check for them.
Checking for Issues with Wiring
One of the most common causes for an AC unit not turning on but not humming is an issue with the wiring. This could be something as simple as a blown fuse or a more complex problem like a short circuit. To check for these types of issues, you’ll need to locate the circuit breaker and ensure the correct circuit is turned on. Additionally, you’ll need to check for any exposed or loose wiring. If you come across any problems with the wiring, it’s best to call a professional to handle the repairs.
Improper Installation
Another potential cause for an AC not turning on but not humming is improper installation. This usually occurs when the unit is installed in an area where the air flow is restricted or the wrong size unit is purchased. In this case, it’s important to ensure that the unit is properly ventilated and that it is the correct size for the area that it is installing in.
Broken Relay
Sometimes the problem may be a broken relay. If this is the case, it’s important to check for any loose or broken parts. You’ll also want to look for any signs of corrosion or any other potential problems with the relay. These are usually quite easy to replace, however, it’s important to ensure that the new one is installed correctly.
Clogged Air Filter
Another potential cause of an AC not turning on but not humming is a clogged air filter. This can restrict the airflow and cause the unit to become overheated. It’s important to make sure that the air filter is regularly cleaned and replaced as needed.

AC Not Turning On But Not Humming: Manufacturer Recommendations & Technician Best Practices
Preventive actions for AC not turning on but not humming issues can be a tricky problem to tackle. Manufacturer recommendations and the advice of reliable air conditioning and heating technicians are invaluable when it comes to avoiding such problems. With the right advice, you can diagnose and repair your air conditioning unit quickly and correctly.
Manufacturer Recommendations
-
Verify the power supply to the AC unit. Check to make sure power is active on the unit. Check the fuses and check the circuit breakers.
-
Check the thermostat. Inspect the connections to make sure the thermostat is receiving power. Change out the batteries if necessary.
-
Clean the condenser unit. Use a garden hose to spray the fins of the condenser coil; dirt, leaves, and grass can block airflow and cause the unit to overheat.
-
Change the air filter. The air filter helps to circulate air and clean air from dust, dirt and other debris. Make sure the air filter is clean and free of debris.
-
Test the indoor coils. Clean the evaporator coil with a vacuum cleaner and brush. Make sure the evaporator coil is free of debris and dust.
HVAC Technician Recommendations
-
Call a professional HVAC technician to inspect the unit. They will make sure the connections are tight, check the operation of the fan, and make sure the compressor is running properly.
-
If a technician is called in, be sure to turn off the power source to the AC unit. This will ensure the safety of both you and the repair personnel.
-
Have the technician inspect the unit for faulty wiring or electrical connections. Issues with wiring can cause the unit to not turn on, but not hum.
-
Make sure the blower motor is running correctly. If the blower motor isn’t working properly, it could cause the unit to not turn on but not hum.
-
Have the technician inspect the refrigerant levels. The refrigerant should be at the proper level for the unit to run correctly.
-
Have the technician check the refrigerant system for leaks. If the system is leaking, it must be repaired before the unit will run correctly.
Additional Considerations
-
Consider using a surge protector on the AC unit to help reduce power fluctuations.
-
Have a professional technician check the air flow through the unit. If there is not enough air flow, the unit may not turn on but not hum.
-
Make sure the unit is properly vented. Poorly vented units can cause the unit to overheat, which can lead to not turning on but not humming.
-
Make sure the air temperature is set correctly on the thermostat. If the air temperature is set too high, the unit may not turn on but not hum.
-
Have the technician check the capacitor for signs of distress. The capacitor helps to regulate the voltage to the compressor, and is the most common cause of an AC unit not turning on but not humming.
By following manufacturer and technician recommendations, you can ensure that your AC unit is running properly and efficiently. Taking preventive action helps to avoid AC not turning on but not humming issues. If all else fails, contact a reliable air conditioning and heating specialist to help diagnose and repair your AC unit.

Frequently Asked Questions
What can I do if my AC isn’t turning on but isn’t humming?
A humming sound is caused by the compressor attempting to start. If the compressor is not attempting to start, it could be due to a power issue, improper setting or defective indoor/outdoor components. First, inspect your power connection to make sure it is properly plugged in and in good condition. Then, check your thermostat to make sure the temperaturesetting is adequate and the system is not in “off” mode. After, try inspecting the electrical wiring and components of both your indoor and outdoor units. If all of these are okay, it is likely a system malfunction. In this case, call a reliable appliance repair service to assess the system and determine the cause of the malfunction.
