Shut off Any AC power (hydro) to it, remove ceiling assy (inside part) and you'll see 4 bolts going up through lower assy, and into base of upper assy (roof unit) . Remove those 4 bolts and any wiring harness connected from lower to upper unit. Lift it off. If your just replacing the upper assy, leave hydro wires hooked up to lower assy , and let it hang, while you clean surface on roof for new install. Re-install 4 bolts and tighten equally until gasket is approx 1/2 thickness it was before tightening. Re-install wiring harness plug in to lower unit etc. If not replacing, but removing entire assy (upper and lower) be sure to Marette and tape hydro wires as well as any 12 volt wires, and tuck away safely. Install a vent on current opening , or whatever you choose.

Need to replace inside AC control switch (Coleman) on 1977 Tioga RV.


If controls are at the ceiling, get model and serial number off bottom of upper (roof) unit and stop at an RV service, and sales place and see if they have new in stock. If not they should be able to order you a new one for around $100 Cdn. You get the whole ceiling assembly . Or contact : http://www.rvcomfort.com/rvp/tech_info/parts_doc.php

RV AC is working fine, but the water is leaking from the ceiling Where is the drain tube on the unit, The AC unit is a roof type, Duo Therm serial # 43404934, Part # 3105459


Normally, the condensate will drain out of the unit onto the roof and off the edge to the ground. Remove your cover inside (probably 2 screws) and tighten the 4 bolts you will find inside. If they are tight, go to your RV supply place and get new roof gasket. Remove the AC and insert the new gasket and resecure the AC to your roof.

Thanks for your question @ FixYa.com

Hi' I have a coleman roof top AC unit on a 1991 Tioga i just purchused a couple of months ago! When i turn on the AC it makes a humming sound...no fans spin or no air comes out! If i let it hum for...


Hi,
The blower motor is seized up...you will need to get up top and remove the cover...then remove the fan blades and the motor and replace the motor....sometimes a temp. fix will be to get WD-40 and then oil worked into the bearings...but that is usually a very short lived fix...
Replacing the motor can be frustrating and time consuming, so you may want to hire someone to do it for you...you may also find that a replacement unit is more cost effective..

Roof top A/C cover removal


The covers just have screws that go from the top down through that hold them on. Once the screws are removed the top cover should come off the bottom I am not sure about the bottom one the whole unit may have to come off for that one.

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.
