Why is my Friedrich 2007 Air Conditioner not cooling properly?
- J
  Joshua MartinezJul 28, 2025
  There are several reasons why your Friedrich air conditioner might not be cooling effectively. It could be an undersized unit, in which case you should refer to an industry-standard sizing chart. Check if the thermostat is open or inoperative; set it to the coldest position and test it. A dirty filter or dirty/restricted condenser or evaporator coil can also cause this issue, so clean them as recommended. Ensure good air circulation by adjusting the discharge louvers and using a high fan speed. For applicable models, make sure the fresh air or exhaust air door is closed. Finally, low capacity due to undercharge or a compressor not pumping properly could be the cause; check for leaks and repair them, and check the compressor's amperage draw against the nameplate.

How to troubleshoot a Friedrich 2007 Air Conditioner compressor that does not run?
- E
  Erik GatesAug 2, 2025
  If the compressor on your Friedrich air conditioner isn't running, start by checking the voltage at the compressor, ensuring it's within a 10% variance of 115V or 230V. Verify that the thermostat is set to the coldest position and test/replace it if it's inoperative. If the compressor hums but cuts off, try hard starting it and directly testing it; if it starts, add starting components. Also, check for open or shorted compressor windings by checking for continuity and resistance. Test the overload protector and capacitor, replacing if inoperative. Test the system switch for continuity in all positions, replacing if inoperative. Finally, refer to the wiring diagrams to check for broken, loose, or incorrect wiring.

What to do if the thermostat does not turn off my Friedrich Air Conditioner?
- I
  ishannonAug 5, 2025
  If the thermostat isn't turning off your Friedrich air conditioner, first, disconnect power to the unit and remove the thermostat cover to check if the contacts are stuck; if they are, replace the thermostat. Try turning the thermostat to a higher temperature setting to see if the unit cycles off. Refer to the appropriate wiring diagrams to ensure correct wiring. Finally, consider that the unit may be undersized for the area being cooled; refer to an industry-standard sizing chart.

  First, ensure the power cord is properly plugged in. Then, check if a fuse is blown or a circuit breaker has tripped; replace the fuse or reset the breaker. If this issue repeats, verify the fuse or breaker size and inspect the unit's wiring and components for shorts. Also, make sure the system switch is not in the "OFF" position and test the system switch for continuity in each position. Finally, examine the wiring at the switch and other components for looseness or disconnections, reconnecting them according to the wiring diagram.

What to do if the evaporator coil freezes up in my Friedrich 2007 Air Conditioner?
- J
  johnmartinAug 14, 2025
  If the evaporator coil in your Friedrich air conditioner is freezing up, begin by cleaning the filter as recommended in the Owner's Manual. Check for restricted airflow by inspecting for a dirty or obstructed coil, cleaning it with a pressure wash or biodegradable cleaning agent. Test the thermostat for shorts or stuck contacts. If there's a shortage of refrigerant, de-ice the coil and check for leaks. Test the fan motor and replace it if inoperative. Lastly, if there's a partially restricted capillary tube, de-ice the coil, check the temperature differential across it, touch-test the coil return bends for even temperature, and test for low running current.

Why does my Friedrich 2007 fan motor not run?
- D
  Douglas LivingstonAug 19, 2025
  If the fan motor on your Friedrich air conditioner isn't running, first test the system switch and replace it if inoperative. Then, refer to the applicable wiring diagram to check for broken, loose, or incorrect wiring. Also, test the capacitor and replace it if inoperative. Check the fan speed switch and replace it if it's open. Finally, test the fan motor itself and replace it if inoperative, ensuring the internal overload has had time to reset.

Why does the compressor in my Friedrich 2007 Air Conditioner run constantly and not cycle off?
- A
  Ashley MillerAug 23, 2025
  Several factors can cause a Friedrich air conditioner's compressor to run continually. An excessive heat load, possibly due to an undersized unit, may be the cause; test the cooling performance and consider replacing it with a larger unit if needed. Check for restrictions in the line, such as a partially iced coil, and check the temperature split across the coil. A refrigerant leak could also be responsible; look for oil at silver soldered connections, a partially iced coil, check the split across the coil, and check for low running amperage. Additionally, check the thermostat's operation and replace it if the contacts are stuck. Finally, refer to the appropriate wiring diagram to ensure the thermostat is correctly wired.
