We have a small 115 volt Sears 'portable' type dehumidifier in
basement. Portable! Well; it has four casters on the bottom and
probably weighs about 50lbs?
Works fine. But occasionally has frozen up solid. Right now it is off
and have a fan in front of it circulating basement air about at 60
degrees to melt the ice.
Right now, as bought, there is a humidistat that switches the whole
thing on and off. There is also a float switch that also switches
everything off when the reservoir is almost full.
Thinking of changing wiring so that the circulation fan, but not the
compressor, runs continuously as long as the unit is plugged in to aid
defrosting.
Any comments or advice please.

You could do that, or if a small exterior fan would be cheaper to run,
that might help also...

Most dehumidifiers freeze up below 65f, there are new units designed
to go much lower, to 45f.

you should be able to attach a garden hose to the dehumidifier tank so
it can drain into a floor drain.
Put a little heat into the basement, possibly open a few furnace vents
to the basement, or add one from the furnace, something to keep the
temperature up.

What your dehum needs is a thermostat, to shut off the compressor when the
coils get too cold. I've seen "freeze stats" on dehum in the past.
