[Shop-talk] Dehumidifier suddenly freezing up

[Wayne]

I'm good with the mechanical and electrical side of HVAC and 
refrigeration, but only superficial on the actual refrigerant loop part. 
But from what I know the evaporator "freeze up" is usually low charge or 
restricted air flow. Might pull the cover off and see if the coil or 
other pathways are choked up with dust or mold. If it really is down on 
refrigerant, much as I hate our society's current "disposable 
mentality", it's pretty much a throw-away.
