How to Fix midea air conditioner won t turn on Step-by-Step Guide
Follow these steps to troubleshoot your Midea air conditioner:
- Check the Power Outlet: Plug a different device into the outlet to ensure it’s working. If the outlet isn’t working, try another outlet or contact an electrician.
- Check the Circuit Breaker: Locate the circuit breaker for your AC unit in your home’s electrical panel. If the breaker is tripped (in the “off” position), flip it to the “off” position completely, then flip it back to the “on” position.
- Replace the Remote Batteries: Replace the batteries in your remote control with fresh ones. Then, try turning on the AC unit using the remote.
- Inspect the Power Cord: Carefully examine the power cord for any signs of damage, such as cuts or fraying. If you see any damage, do not use the AC unit and consult an electrician.
- Clean or Replace the Air Filter: Locate the air filter (usually behind a removable panel on the front of the unit). Remove the filter and clean it with water and mild detergent or replace it with a new one. Allow the filter to dry completely before reinserting it.
- Verify Thermostat Settings: Make sure the thermostat is set to “cool” and the temperature is set lower than the current room temperature.
- Try the Manual Power Button: Most AC units have a manual power button directly on the unit itself. Try using this button to turn the AC on. This will help you determine if the remote control is the problem.
- Check the Control Panel Lock: Some units have a child-lock or control panel lock feature. Check your user manual for instructions on how to disable this lock.
- Reset the AC Unit: Some units can be reset by unplugging them from the outlet for 15-20 minutes. After that, plug them back in and try turning them on.
- Examine Condenser Unit (Outside if Applicable): If your AC has an outside condenser unit, visually inspect it for obstructions (leaves, debris). Clean around the unit.
Fix the Issue Without Buying Parts
Before spending money, try these free methods:
- Reset: As mentioned earlier, unplugging the unit for a period can sometimes reset internal systems.
- Cleaning: Regularly cleaning the air filter is crucial for maintaining performance.
- Inspection Tips: Check for loose wiring connections where visible (always unplugged!). Look for ice buildup on the coils.
- Maintenance Basics: Schedule regular professional maintenance to prevent future problems.
When Replacement Might Be Necessary
If you’ve tried all the troubleshooting steps and your AC unit still won’t turn on, it might be time to consider a replacement. Common parts that fail include the compressor, fan motor, or control board. The cost of a new Midea air conditioner can range from $200 to $1000 or more, depending on the size and features. Repairing the unit could cost several hundred dollars, so you’ll want to weigh the cost of repair versus replacement.
Safety Warning
- Always unplug the air conditioner before attempting any troubleshooting or cleaning.
- Never work with electrical components while standing on a wet floor or with wet hands.
- If you are uncomfortable working with electricity, contact a qualified electrician.
- Do not attempt to disassemble any parts of the AC unit beyond removing the air filter.
Tools You May Need
Here are some simple tools that may be helpful:
- Screwdriver (Phillips head)
- Flashlight
- Multimeter (for testing voltage, if you are comfortable using one)
- New air filter
- Cleaning supplies (water, mild detergent)
FAQ
Here are some frequently asked questions about Midea air conditioners that won’t turn on:
-
Q: Why is my AC not turning on even with new batteries in the remote?
A: The remote sensor on the AC unit might be faulty. Try using the manual power button on the unit. If that works, the remote sensor is likely the issue. -

A: This could indicate a short circuit or an overloaded circuit. Contact an electrician to inspect the wiring and the AC unit. -
Q: Can a dirty air filter really prevent my AC from turning on?
A: Yes, a severely clogged air filter can restrict airflow and cause the AC unit to overheat, triggering a safety shut-off. -
Q: Is it normal for my Midea AC to be making a humming noise but not turning on?
A: A humming noise often indicates the compressor is trying to start but failing. This could be a capacitor or compressor issue, requiring professional repair.
