Question about Keystone Computers & Internet
The unit is giving me an EC code
You can try cleaning the humidity sensor, which is on a circuit board
housed in a nylon clip attached to the cooling coils.
The sensor is in a plastic clip, which can be opened up and cleaned.
Some report success. Didn't work for me.
I ended up rewiring the unit so that a 5v control
line from the lower relay board goes through the SPDT bucket full switch,
turning on the control board when full (so it beeps), but otherwise
enabling the compressor and fan. The fan and compressor
are controlled by relays, which are driven by a ULN2003AN
relay driver. I fed the empty side of the full bucket switch back into
the relay driver to turn on the compress and the fan on high.
I plan to put a dehumidistat in series with this control line;
now it just runs till the bucket is full. A Broan DH100W dehumidistat
is 20 bucks. Could also put in a rotary switch to control the fan speed,
but for me high is enough.
I think this machine is made by Goldstar for Kenmore and Delonghi.
Stuff is just made to break and through away these days, which is a shame.

HI.Error code 1 usually informs us that the filter needs cleaning.This might be needed qwhen the unit runs for 740 hours or more.So you need to manually clean the filter by removing firsst the cover then .you have to unscrew.remov e the filter located at the backmost part of the a/c unit.You can actually apply pressurized water to removed debris or apply detergent to soften hard debris.Thank you for choosing fixya.

Hello friend, thank you for your inquiry!
I understand that you are getting an "EC" error code on your Frigidaire air conditioner. However, it appears "EC" is an invalid error code. It is possible that the error code is missing characters? I show that the error code "ES" or "CS" is valid. In the meantime, I suggest resetting your air conditioner. You can do this by flipping the household circuit breaker for roughly ten minutes. If resetting the power does not correct the issue, could you please inform me of the new error code or if your air conditioner continues to display "EC". I look forward to assisting you. -Matt
