Coleman TSR RV air conditioner doesn't blow cold- Doesn't need a charge

We have a 1986 Terry Taurus triler with an a/c unit that only says "Coelman TSR" on it. No model number.

The numbers that are on the label for the thermostat switch are:

6701 340
A30 1813 00
P166 24 SA
The knob that controls the heat and the a/c temperature does not appear to be sending an electrical current to the components in the rooftop unit. The fan works on all settings, but we don't get heat or a/c; only ambient air temperature air flow.

A friend tried to give it a freon charge, but that didnt allieviate the problem because the compressor does not appear to be turning on.

The other things listed on the main unit re:
Heater amps 13.2
Fan motor amp 01
Compressor RLA 11.0
Compressor LRA 61.0
Cycle 60 1 phase

yeah, it could be getting low on freon but you also could turn up the ac a bit... if your running at 68 degrees or something turn it up to 72 and it wont freeze up as quick.

SOURCE: I have a Coleman model FL 28-R electric fireplace,

There is a fuse located over the heating element in front of the fan. It sits over a small slot above the heating element (probably to cause it to stop working by design). Yes I'm a pessimist. It can be bypassed if it is an emergency by wiring across it. I'm trying to find the replacement fuse now (10amp jet 250v #00575) If you find it please send info to I hope we all get our heaters working, for $250 + dollars you'd expect it to last longer than 1 month.

This flame is not likely going off on a high limit due to clogged filters as suggested previously because the unit goes off on safety before the blower comes on. If it works sometimes and not others it is most likely a flame sense issue or an electronic problem. If the boards logic tells the inducer to keep running if it thinks the flame is lost this may be your clue. You can attempt to find the red LED trouble light on the circuit board(or in burner compartment) and this may tell you exactly what the problem is but you may need to tape the door interlock switch so you don't loose the code when you open the blower compartment. You can clean flame sensor with very fine sandpaper or steel wool but replacement is usually the best.

It could be that the flame is " Rolling out" of the burner compartment and hitting the safety device known as the "ROLL SWITCH" If this happens all the time you probably have a split / cracked heat exchanger or a heat exchanger that has holes in it. The holes allow the air pressure from the indoor blower to enter into the burner tubes and blow the flame back out of the burner compartment...not to mention allowing poisonous CO [ Carbon Monoxide ] to enter the air stream that goes into the heated space of the people down below. The holes don't have to be very big for this to happen and if the heat exchanger is split along the factory will be very heard to see unless you have the heat exchanger heated up for a while. Heat exchangers are the second most expensive part of a rooftop unit right after an A/C Compressor. they're not too difficult to change but you have to know what you're doing specifically when resealing all the sides and edges so CO doesn't leak out of a seam and kill everyone down below.

Colemans hot water on battery ,plenty of gas .works on cold,but not on hot

If it is out of warranty there is a fuse inside them that is covered with a light rubber coating, it is the common glass style fuse. That may be causing your issue assuming the battery is ok. The batteries die regularly too especially if it hasnt been charged and is sitting around.

Water system in my Coleman pop up not working

Make sure you have a water regulator connected to the water source before connecting it to your RV or the pressure could blow out your plumbing. The force of the water coming from the faucet can be too much for any RV and a regulator can be purchased from RV dealers, camping world, and even some Wal Marts carry them.

The air conditioner on my pop up camper is loud and vibrating

sounds like the compressor in your air conditioner has a broken spring in it,you can not take the compressor apart to fix,has to be replaced(cashy).I assume your camper is shaking,and the noise only happens when you turn on the air.
