Coleman TSR RV air conditioner

We just bought a 1996 motorhome & the AC panel on the inside has a Solar Monitor light on it. What does this do? Can we put a solar panel on the motorhome?

There should be a solar panel on top of your roof top air conditoner. There is a quick disonnect for the solar panel. If the monitor light illuminates the solar panel is working.

Need solar panel monitor for coleman TSR

Wire it direct to batteries. It puts out very little amperage, so not to worry about overcharging the batteries. It's only basically a trickle charge.

Coleman tsr rv air conditioner leaks into rv when running

It probably has a clogged condensate drain. Take off the cover on top the RV and check hoses or tubes leaving unit for debris or lint. Often this water is used to help cool the condenser so look for leaves pine needles etc in the pan. There may be a cover you can remove on the evaporator section that will allow you to clean the collection pan and hose or trough. Is it possible the RV is far enough out of level that the condensate can't "run uphill"? Always power off while working on this unit unless you are electric savvy. Good luck!

Coleman tsr mach 3 RV Air Conditioner

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $ you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know
