Ac/heat pumps

A few days ago I responded to someone that our ACs were 13 years old and no problems.
Actually they are 115 years old.
Th last few days our rear air was making noises. Last night it seized up. Te capacitor tried to start it but couldn't.
I was making plans for about 1800.00 to replace it.
Colman, today puled it apart. The fan had slid down the shaft and bound it up.
They replaced the fan and put an extra screw in the shaft. I won't slide down again.
Now or the other half.
Didn't think enough air was coming through the registers and not cold enough.
Pulled the filter housing and the metal plate and a blast of very cold air hit me.
They showed me that no gasket was installed, between the unit up top and the discharge,just some pieces of ill fitting fiber glass board.
Some of the air was just going back through the cooling circuit and some elsewhere.
The used metal tape to seal up both ACs or heat pumps.
Put the filters back up and we have cold air not seen n this coach from the time it was built.
So when you think yours has seized up, just check on the fan first.
and check your hear pump/ac seal to the register duct.
When we get home I'm going to check the registers,where the air comes out, for seal.
They are only supposed to check the ac units but there are many here at the Rally experiencing similar problems and on Coleman's list.
I had read of the problem of unsealed duct work before, here on the forums, but had been assured by someone mine were fine.
It is right at 92 outside and I'm cold. So I'm getting up frm the table to adjust the thermostat.

    My main thermostat was mounted on an exterior wall. I took it loose and put a piece of styrofoam behind it and remounted it with a gap between it and the side wall. This prevents it from picking up a false temperature reading and has been working fine since then to maintain a constant temperature inside the coach.


    Clever!

  • I have another problem now.
    There's a colony, of lost penguins, knocking on the door, wanting in.
    Thermostat was turned up to 75 but the little thermometer, we keep in the fridge,says it is 63. Wife is wrapped up in a blanket and I'm shivering so much, I can but hardly type.
    Just now rear unit cut off. Probably frosted up.
    I'll have to find someone to find and fix the sensors, tomorrow.
  • The leaking around the ducts is what I found on my AC/heat pump as well. I sealed the ducts with the aluminum duct tape and then coated the duct tape with the white latex duct seal which is thick but can be brushed on. Once this duct seal dried, there was no chance that the tape could come loose and it has stayed sealed for four years of bouncing down the road. It is nice to have all of the conditioned air coming inside, instead of in to the roof structure or outside.
