RE: Air Conditioning
Joe
Maybe your AC is "Short-looping"?
Air is drawn from the coach's interior into the ceiling unit. This warm air is then blown across the cold evaporator and into the ductwork. This cold air mixes with the warm air and the cycle repeats. Over time, the warm air gets cooler so the AC cools increasingly cooler room air.
But, if there's a cold air leak inside the ceiling unit, that just cooled air could be immediately returning to the evaporator. If the unit is equipped with a thermistor, that sensor "tells" the system that the interior is COLD and the compressor shuts off...keeping the unit from freezing up.
To check for this condition, remove the ceiling grille.
With the unit running, CAREFULLY insert your hand up into the exposed air intake...carefully because there's 120 volts and spinning fan blade that might be exposed.
You're checking for any cold air being blown into the intake...any cold air. If you feel any fan-forced air against your skin you'll want to seal that leak.
Use the metallic foil duct tape to thoroughly close off any leaks...don't use that cloth stuff unless you want to repeat the process every few years.
