My dehumidifier is displaying an error code. What does it mean? Your dehumidifier has sensors to monitor for various conditions that may prevent the unit from operating in a normal manner. Please refer to your user manual for error codes and operating instructions for your specific model. Common dehumidifier error codes and messages can be found in the list below:
ES or E1 - Temperature sensor error
E2 - Defrost sensor error
AS or E3 - Humidity sensor error
P1 - Unit is in defrost mode. Defrost process should take a minimal amount of time before the unit returns to proper functioning order. If the unit display P1 code for more that 1 hour, unplug unit and allow to manually defrost for 4-6 hours.
For the above error codes, Power the unit off, and then unplug the unit for 15 minutes. Plug in and power on. If the issue persists, please contact customer service.
EC - Ambient temperature error. The environment where the unit is operating is either too cold or too warm. Make sure the ambient temperature is suitable for the unit (41°F - 95°F).
LO - Temperature too low error - Current room temperature is below 32°F. Make sure the ambient temperature is suitable for the unit (41°F - 95°F).
HI - Temperature too high error - Current room temperature is above 122°F. Make sure the ambient temperature is suitable for the unit (41°F - 95°F).
P2 - Bucket is full. Empty the water bucket and reinstall it. How do I drain my dehumidifier?

usually, owners manual defines error codes. Otherwise google "(make, model) error codes".
If it isn't blowing warm air, then the compressor isn't working which would be why it isn't making any water.

The cold that you describe may be just unconditioned air? If you are certain you can hear the comp operating for a couple of minutes, and then the heat starts, I would guess it is a reversing valve issue if it's a heat pump and it probably is. Or the control board acting up. I've had a lot of issues with the boards in the Amanda PTAC units. I can't remember how to configure it, but if you Google "Amanda ptac configuration", there is a lot of info online. May try a reset method first. Hope this helps!

probably a gas leak or the compressor is not working properly

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

It means the unit is low on gas

You need a pro. To try and diagnose this online would be extremely time consuming and dangerous.

What's the temp been out side? If its over 95 degrees only expect you air to blow at about 75. It's an air conditioner not a cold air maker.

if both vents are blowing air in general then you may need to get your air conditioner recharged, but if the front vents aren't blowing at all then you may just have a jammed vent flap and you can fix that from under the hood next to the blower motor. check you rowners maual for the exact location

This unit is use in motels etc. Check the ouside coil ( conderser) from the inside (discharge fan ) for dirt. Most of these units are floor level . This can cause a unit to short cycle ( cold air is at the floor) .
