The freezing up could be caused by a number of things.

  • Poor Air Circulation - this may be caused by a dirty or poor air filter you coils will end up dirty as well. Have it cleaned out. Another reason could be is a blower that is not providing enough air to your coils. You need to check for obstructions.
  • Outside Temperature - temperatures under 60 degrees outdoor air conditioning units tend not to function as well. When the temperature drops the system begins to not function properly and freeze ups can occur. The simplest method is to not use your unit when the temperature cools down and open your windows or doors. If that's not a option you will probably need to have a ambient temperature control installed in your system.
  • Low refrigerant charge - there could be leaks in the coils and if there are loose fittings or weak solder joints it could be leaking from those areas. If you've determined the refrigerant lines are not leaking than it may just need to be recharged
Thank You

If you have the travel trailer do the obvious and take a tape measure out and measure it. If you don't have the travel trailer contact jayco trailers and talk to the sales manager.

Interior lights inop jayco pop up tent trailer


I have a 99 Jayco Eagle Tent Trailer and had this issue of no interior lights. I discovered that the kill switch was stuck in the off position. On my trailer, it was located on the inside of the roof about 1 ft. from the end of the roof where the electrical wires come down the black protective tubing. This is on the road side of the trailer.

I have a travel trailer with a coleman 7300 roof top ac unit. the unit will blow cold air but water leaks thru the plenum. i was told by the previous owner that it needs a new seal. i would like to fix it...


If it's leaking inside where filter cover is, then real good chance the drains being plugged is the only problem. If water (condensation) not running off roof when operating in cool mode, then I'd bet drains, which are located under unit on roof, and you should see them sticking down like buttons. They have a hole in side that needs cleaning with a pipe cleaner or similar to open them up. If need be, shut off power to unit and remove top cover on roof unit and look for the drain holes in base, and clean them out. If water comes in while raining, but AC not running, then it's gasket. That is remedied by removing ceiling assembly (just screws) and 4 bolts that pull/hold the upper and lower assemblies together, unplug wiring to upper unit, and simply lift it off, change gasket and re-install. Tighten those 4 bolts equally when gasket is aligned properly over hole, only until gasket is approx 1/2, original thickness. Plug harness back in and your done. (about an hours work.) Only other thing that may be wrong is styrofoam drip tray for cooling unit, under cover on roof may have a crack , allowing condensation to leak in. If that 's the case, you can try to find a sealant compatible with styrofoam to seal those cracks.

How difficult / expensive is it to install a heat strip in a Dometic roof top AC? The unit I have has a mark on the knob for heat, but I suspect it was never installed.


Fairly easy. The only thing that you must figure out is how many amps the heat strips will draw. Make sure the fuses and the breaker switch can handle them. And be aware your electric bills will shoot up.

Seal for roof top ac unit


I just spoke with the mechanic at my RV dealership and he said the sticky side goes on the a/c unit. You only have to turn it on it's side to do this. Just wait 1 hour after re-installing the unit on your RV before turning it on.
