I decided to do the repair myself. I opened up the unit, and found the time delay board. But, I found four wires connected to the board (red, white, black and blue), not three. I assume that I should just cut each of these four wires to disconnect them from the board, then remove the board, and then connect two of the four wires to the contactor (relay)and apply electrical tape to the ends of the remaining two wires. Which of these four wires are the low voltage wires to connect to the contactor? How can I tell which side of the contactor is the low-voltage side? Thank you.

Firstly the wires meant for low voltage side should be considerably thinner in comparison to the high voltage one and much stiffer too. If you can still power up, then those carrying higher voltage would make the tester glow by just holding the tester close but not touching the tester starts glowing. Generally the ground wiring is black and one which is known as the live is blue. Before cutting them I would suggest that you let the power in, but do not operate any controls. The tester that I mentioned before, the tester will help you differentiate the high & low voltage lines. Then when working ensure that the plug has been removed from the socket...........sodeep

What does H1 code indicate?

Hello E, I appreciate your post!
I see that your Frigidaire air conditioner is displaying an error code of "H1". I have reviewed the air conditioner and the "H1" error code could be an "HI". The "HI" error code means that the room temperature is above the display range. I would recommend performing a reset on your air conditioner. In order to reset the air conditioner you need to unplug the power cord you can press the reset button and then the test button that should restart your air conditioner. If that does correct your issue I would recommend seeking assistance from a professional technician for proper diagnosis and repair. I hope this information is helpful for you. -Matt

Te 522 error EE

EE stands for Energy Efficient. The problem could be:

1) a bad thermostat 2) inadequate ventilation (blockage) 3) a bad controller board if the unit does not come on following this display.

The manufacturer pretty much decides what these specific codes mean. You might have to contact them.

P-1 code

Hello Friend, thank you for allowing me to assist you!

If you are getting an error code P1 on your Frigidaire air conditioner, normally it indicates that the bottom tray is full. Carefully remove your air conditioner to a drain location and remove the bottom drain plug and allow the water drain. Then restart your appliance and P1 symbol should disappear after you have let your appliance run. However, if the error code continues, at this point, I would recommend reaching out to a professional to proceed further. - Z

Frigidaire fas257q2a2

Hello Friend, I am happy to assist you!

I understand your Frigidaire air conditioner (FAS257Q2A2) is displaying error code A5; however, it appears the correct error code is AS. Error code AS typically indicates that your air conditioner is experiencing an issue with the ambient thermistor. I would strong suggest contacting a professional to check the wiring between the main control board and thermistor. A certified technician would generally replace the faulty part after proper diagnosis. Best regards! - Z

I get a EE code on the display. What is it?

EE is a high pressure error code. The unit may be to small for the room deppending on what temp it is outside.If its over 95.f The a/c is probably overworked.

One way to solve this would be to cool down the coils outside.Spray water lightly on the outside of the unit too cool it down which will bring the pressure down also.

This is possibly either a complete outdoor pc board error or an E-Prom error on the indoor pc board. You can try shutting down supply power completely for a minute and then switch on. These units also have a delay timer system which does not like to be switched on, off repeatedly in a short period. Please also check for reset button on the outdoor pc board. Hope this helps.
