The tank is empty but the full light stays on
The full light normally comes on when the tank is full. Emptying the tank and re-installing the tank should allow the system to reset. However, if the tank isn't pushed in all the way... the full switch and indicator light will be fooled into reporting a full condition. My suggestion is, first pull out the tank, look at the float and the tank full switch. Become familiar with these two items and confident that 1) the float is not stuck in the up position; 2) the tank full switch that the float is supposed to actuate will toggle (press your finger against it and let it return.) After this exercise make sure the tank is seated all the way in place. If your issue is mechanical, its easier to fix than if it's electrical, and if it is electronic... (just pray that it isn't).

Unit runs but the coils dont get cold
The compressor should be cool near the bottom and hotter at the top. If it runs but the coil is not cool, it probably lost its charge. Developed a leak and lost all the refrigerant.

Unit was charged w/ 10.6 OZ of R22 and don't seem to be working very good?
About 61 PSIG or 33 Degrees F. If you look at the gauge on your refrigeration manifold it will give you the numbers. What is Max, it changes with temperature and humidity and without very involved controls the absolute max will not be realized over the normal ambient operating range. Good Luck

The float is broken
If all you need is the Styrofoam float, you're in business, If it's the entire float arm you're not so lucky.
See ref numbers

My dehumidifier freezes up.
I don't think there is anything wrong with your machine ... What I think you should do is get another fan and blow air onto the rear of your dehumidifier. I also think you should select a higher setting until you get some of the water out of the air. When you get down to 80% for example (evidenced by the machins turning off - set it then to 70% and so on until you arrive at the moisture content you desire (50% is usually considered perfect.) You might also consider adding another machine to help the first, same setup with a fan blowing on it.
This is what I did when my dehumidifier did the same thing yours is doing.
Thanks for your quesiton @ FixYa.com

Why does my dehumidifier run al the time ,i have
The 45% setting is too low and the setting is never satisfied, so the unit keeps running to try and reach 45%. Try setting to 50 or 55, this is a very comfortable range. I was not clear on the room temperature being at 55 degrees. Is this what your thermostat is set to or is this the actual room temperature. Brrrrrrrrrrrr

Wont remove any water
There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2..
1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
(No LED display), set the humidity extraction knob on Maximum.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air
temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.
If
none of the above solves the problem, it may be a case of the
compressor needs to be recharged with refrigerant gas or that the humidity sensor has failed. These things usually occur in units that are
5 years old or older. It's rare in a unit younger than that. But, it
can happen.
I hope this information will help you to troubleshoot & solve the problem. Thanks for choosing FixYa.

What volt extension cord should I use with this
Voltage and amperage are two different things. Most dehumidifier manufacturers do not recommend the use of an extension cord (check your Owners Manual). However, if you were to use one, it should not be longer than 6 feet and should be a minimum of 14 gauge wire with a ground.
Hope this helps and thanks for choosing FixYa.

My dehumidifier runs like a
Mike, there are 5 things that could be causing the problem you're having. So, before you ruch out to buy a new one, try troubleshooting this one first.
Turn the unit OFF & unplug it before attempting any troubleshooting
1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit, set
the humidity extraction level knob on Maximum.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. Ambient air temperature at floor level is between 40 - 60 degrees.

If
none of the above solves the problem, it may be a case of the
compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are
5 years old or older. It's rare in a unit younger than that. But, it
can happen.If none of the above solved the problem, it ma be time to start shopping for a new dehumidifier. As repairs can often cost almost as much as a new unit.

Lcated in basement, quite humid; humidifier runs

Where can I buy a new float assembly?
Unfortunately, the entire float assembly (Part # CRCDFD5404-010) is no longer available and their are no interchangeable substitutions.In lieu of that, if you can hook it up to a hose for continual drainage, you wont need the float assembly.
Hope this helps and thanks for choosing FixYa.
