    Same problem for me. Runs and blows cold air for an hour or so and freezes up then the unit boggs down with very little air blowing into the RV. Mine is a Duo Therm 15k Quik Cool roof top A/C and is 3 years old. Changed out my T/S earlier becuase it was "short cylcling". That seems to have went away. Cleaned coils but still freezing up.

How do i deal with the dripping of water from my Mitsubiishi split system from inside unit? Will putting the unit on 19 and then turning it full bore clear over condensing?


NO
the water is condensation from the humidity in the air turning to water on the cold evaporator core
normally it drips into a tray and drains away outside
if it is inside ( running down the walls it indicates
the drain hole and tube is blocked or the evaporator core is covered in gunk and holding the water up and not dripping where it is designed to
Call an accredited ac specialist shop to clean the fins and drain tube

We have royal red furnace to heat our home.The fan dose not stop.


Details.......does the furnace function normally otherwise? Might just be a stuck fan switch. Make sure the thermostat hasn't been set on Fan ON setting or summer air circ. on older furnaces.
Find the fan switch and tap it and see if fan quits. If it does,fan switch is bad.probably. Always make sure your air circ. filter(return air to furnace) is replaced every 3 mo. or so,too. don-ohio (:^)

Cooloing is not coming down from room temperature


The unit needs service. Call a technician! You can:
Check your air filters
Clean outdoor coil by turning off all power at breakers and tstat, clean o.d. coil with water hose
Inspect indoor coil (if you can) for build up or debris
Other than that? May be low on freon. A service tech will cost $ BUT not having the unit service will cost more due to electrical consumption and excessive run times shortening the life of the system.

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

I have a Coleman Evcon electric furnace, the blower fan runs constantly and I have to shut the breaker off inside the front cover to turn it off. The switch is on auto and it runs even when the thermostat...


It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.

A/c fan not working=thermostat is working(central a/c system)a/c


The fan on the outside unit is powered from it's 240 volt source. Check that the breaker for the outside unit is not tripped. Also, a contactor is inside the outer unit that starts the fan - it may be faulty.
