Yeah, I didn't explain that well. The drip on the floor is from the base o f the dehumidifier. I've tried running it with the hose, or with just the internal tank, and it still drips from the same spot. I took the hose out, connected it to the garden hose, and ran a snake up it with water flowing so I know it is clear.
I've always thought a frozen coil was beyond repair on a dehumidifier.
Let me think out loud: 3 reasons for a coil to freeze, right? Low charge, which means a leak, unfixable; Low air flow, not the case with these units. Bad TXV - do these even have one or are they cap tubes? Either way, not fixable.
I don't think there's any metal to rust on these, it's all plastic, but I'll look.
1) Low charge, which means a leak, unfixable; CY: Yes, some times a low charge will result in low evaporator temps.
Low air flow, not the case with these units. CY: Many dehum pass air over the evap, and then through the cond. Very often, dust clogs and reduces air flow.
Bad TXV - do these even have one or are they cap tubes? CY: Usually cap tubes.
Either way, not fixable. CY: Can also be low ambient temp in the cellar. Dirty coils can be cleaned. Also the unit may be in a confined space, and unable to "breathe". Though, this would lead to higher temps as the heat from the motor.
