What H3 or E5 means

H3 and E5 on Frigidaire dehumidifiers with a digital display, in the FFAD, FFAP and FGAC families, mean compressor overload protection has engaged. The compressor has gotten too hot or drawn too much current, so the unit shut it down to protect it. Poor clearance around the unit, a dirty filter or a room outside the design temperature range of 41 to 89 degrees Fahrenheit are the first things to check.

Common causes of H3 or E5

Too little clearance around the unit
A dirty air filter limiting airflow
Room temperature outside the 41 to 89 degree range
A compressor or its start parts working too hard

✓ One safe check you can try

1. Unplug the dehumidifier and let it cool for a while. 2. Move it so there is open space on all sides and clean the air filter. 3. Make sure the room is between 41 and 89 degrees Fahrenheit. 4. Plug it in and restart; if the code returns, call us.

! Why to stop there

Airflow and room conditions are the common causes, and we check them first.
If the code returns in normal conditions, the compressor or its start parts need testing.
We do not ask owners to open the unit, and we tell you plainly if an older unit is not worth repairing.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

H3 or E5H3 or E5 questions

What is overload protection on a dehumidifier?

They mean the compressor overload protection has stopped the compressor because it got too hot or drew too much power. The unit needs to cool down before it can run again.

How long should I let it cool?

Unplug it and give it time to cool, then restart it in a cooler, open spot. If the code returns soon after, the problem is not just a hot compressor.

Can a dirty filter cause H3 or E5?

Yes. A clogged filter restricts airflow and makes the unit run hotter. Clean it first. If the code keeps coming back in a clear, normal room, the compressor system should be tested.
