How to Fix and Troubleshoot a Friedrich AC

Quck answer

To troubleshoot and fix a Friedrich AC, follow these steps:

1. Check the power supply: Ensure that the AC is properly plugged in and that the power outlet is functioning.

2. Clean the air filters: Dirty filters can obstruct airflow and reduce cooling efficiency. Remove the filters and clean or replace them if necessary.

3. Check the thermostat settings: Make sure the temperature is set correctly and that the fan mode is appropriate for your needs.

4. Inspect the condenser coils: Dust and debris can accumulate on the coils, hindering heat transfer. Clean the coils using a soft brush or vacuum cleaner.

5. Verify the drainage system: If the AC has a condensate drain, ensure it is not clogged. Clear any obstructions to prevent water leakage.

6. Test the remote control: If the AC has a remote control, check the batteries and ensure the signals are being transmitted properly.

7. Contact customer support: If the issue persists, reach out to Friedrich customer support for further assistance or to schedule a professional repair.

By following these troubleshooting steps, you can identify and resolve common issues with Friedrich AC units, ensuring optimal performance and comfort.


Friedrich air conditioning units are available in different models, including portable, window, and central units. Some units may encounter common issues, such as frozen lines, power problems after outages, and difficulties in cooling hot rooms. By attempting to fix a Friedrich unit yourself, you can save money and avoid frustration. If you are unable to resolve the problem, it is advisable to contact a technician or Friedrich customer service for further assistance.

Step 1

If the Friedrich unit continuously blows fuses or trips the power breaker, unplug it from the wall power outlet. Check the circuit-breaker box to determine the maximum power load the circuit can handle and ensure that the appliances sharing the circuit do not exceed the load limit. If there are too many appliances on the same circuit, unplug some of them and connect them to a different circuit.

Step 2

If the unit fails to turn on, unplug it from an extension cord. Some Friedrich units are not compatible with extension cords. Plug the unit directly into a grounded power outlet.

Step 3

If the unit fails to turn on after a power outage, press the “Reset” button on the Friedrich plug. The power restoration may have caused the plug’s internal power-surge protector to trip. Keep the “Reset” button pressed after pressing the “On/Off” button on the unit until the unit turns on.

Step 4

If the Friedrich air conditioner seems to run too frequently, turn on exhaust fans while cooking or taking a shower to remove excess heat from the room. Avoid using large appliances that generate a lot of heat during the hottest part of the day. When the unit has to compete with a significant amount of heat, it works harder than usual.

Step 5

If water drips into the room from the unit, raise the window that holds the window unit in place. Hold the unit securely and reinstall it at a slight tilt towards the back. This will ensure that any excess liquid drips from the air conditioner towards the back, near the drain pan, instead of running along the bottom towards the front and inside the home.

Step 6

If the Friedrich fails to cool when the outside temperature is lower than approximately 65° F, either turn the unit off or run the fan only. If the outside temperature is lower than the room temperature and the lowest thermostat setting on the Friedrich, the unit may freeze while in use. Adjust the thermostat to a warmer setting and run the fan on low, or turn the unit off completely.
