I do not provide Icemakers in my fridges I disconnect all ice makers in my rentals if the fridge comes with one.

A disconnect there I think

They would not address non-compliance issues with the tenants, as I would handle that myself as the property manager.Prior to Winter the elf would check weatherstrips on doors and windows, install weatherizing faucet covers and storm windows, disconnect garden hoses, disconnect air conditioners, and put them away.

There was prep that had to done before the fire department could burn the house (disconnecting utilities, asbestos survey, demo permit, etc).

And you can test that if you choose by disconnecting temporarily the ground wire from a GFCI and pushing the test button, and it should trip. 

I have located contact numbers listed for the owners but all are disconnected.

As cap rates don't drive appraisals in smaller units, there can be a BIG disconnect between rents and appraisals so I watch it (Duplex rented for $1,600/mo appraised at $86k, 4plex rented for $2,050 a month appraised at $165k).

It's a nice feature to have, could make the home more rentable, and no more maintenance than a standard furnace.On the other hand, my guess is they probably disconnected it for a reason so maybe it doesn't even function.

I called my usual guy and his phone was disconnected.

There is a disconnect as policy.
