Having a problem with our Dometic A/C.
It seems to be blowing only cool air now, not ice cold like it was our last trip out.
Now, the temps in Texas have warmed up and humidity is up as well. We got to the campsite around noon and the inside of the trailer was hot (around 90). So we set the A/C to 72, fan on auto and opened the quick cool dump vent then went to the store for supplies. When we got back, the inside of the trailer was still hot and the ac unit was running fan on high but not blowing cold. Occasionally little ice chunks would spit from the return side.
So I opened up the filter intake and looked up and touched the evaporator coil it was also not cold. I could see condensation dripping from the roof gutter outside like normal operation.
Jumped on the forum and searched.
-I reset circuit breakers, ran on fan only hi setting, then switched back to cool, same results - no cold air.
-I taped up the gaps in the divider with A/c foil tape, thinking that the cold air was leaking to the uptake - no improvement.
So next morning, temps fell to upper 60's outside and the ac unit seemed to finally catch up. I used my digital thermometer that has inside temp and a remote temp sensor for outside. I hung the outside temp sensor from the nearest duct register:
At duct - 68 degrees
In RV - 72 degrees
This next day was overcast and only got to about 80 but the temps in the RV steadily increased by the time we left:
At duct - 73 degrees
In RV - 79 degrees
Thermostat setting - 72
Is this normal?
Is there anything I'm missing or should I schedule a dealer visit?
