RV Roof Airs, not so cool

1989 Roof RV Air Conditioners...they are working OK, just not great. Not getting better or worse with use. What goes bad to make them not work as well as they should? If freon is leaking, should'nt it all leak out? Don't want to spend $200 just to be told time to replace. Going to check pressure tonight, as I found the attacment for gauges is allready in place. Only the low side has a tap, safer I guess. All grills are clean, as are the coils. What has the shortest life?

Low side is 65 at high speed. Have not done the temp check. It does have a clamp on port only on the low side. I hear they are prone to leaking.

Re: RV Roof Airs, not so cool

After you check the pressure, get back with me. Age is always a factor with proformance. But really, unless it is leaking freon or has a defective part, the unit should work fine. Measure the temp drop across the coil. Meaning from the intake to the output. Get back with me.

Why rv ac condensate leaks into rv

Drain holes on underside of unit on roof are probably plugged. Need to get up and look under and use a stick or similar to unplug drain holes. Should have condensation running across roof , if not, the drain holes are plugged. If worse comes to worse, may have to remove cover, only takes a minute, just be sure to shut power off prior.

A/c unit vibrates entire rv. could not find any

You may have to remove cover on roof and check condenser fan as well. That will also allow you to observe for possible fan wobble, bad compressor mounts etc. Please shut power off at breaker until you have cover completely off, and be real careful for wasps, and roof may be slippery if wet, or early morning dew on it. Stand back, hands back and have someone turn it on.

When we turn the AC on, after a couple of minutes we hear a hum which lasts about a 1.5 minutes then shuts off. No fan air movement or cooling detected. The unit is 5 years old. We RARELY use it and when...

Go up on roof and using a stick or similar, poke it through the air holes in side & try to turn the fan blade at rear of the air conditioner. Make sure it's off at the time. Try to get 2 or 3 complete revolutions of the fan blades, then try turning it on fan only first,and let it run on fan for a few minutes, then switch to cool. If worse comes to worse and you can't get blades to turn, remove cover on roof (watch for wasps & bees) and spin fan blades a few times by hand, step back & have someone try fan only. If that works, then try cool. Sometimes they get a dead spot from sitting, and that will get it going again, 90% of the time. Let me know how it goes.

Relay (?) sticking Dometic RV rooftop AC

Go up on the roof of the unit and remove the AC Shroud. With the unit running, see if you can pinpoint where the sound is coming from. The only thing on the entire AC that would make that much of a vibration would be the fan motor. Not sure what would cause the fan motor to do this. The compressor may do that but only if the windings are bad and then it would not be cooling.
