AC with heat pump problem????
I have a new 2017 RV with a Dometic 15,000 BTU air conditioner. The AC is equipped with a heat pump. The heat pump was working great. Now the heat pump trips the breaker after 3-4 hours of use....

dougrainer, Paper work doesn't say what model it is but the model number on the warranty is 651816CXX120. The unit is ducted.
CA Traveler, In my discussion with Dometic yesterday they informed me that the heat pump will operate in temp range of 32 to 55 deg. F. I've found that at temps below 37 Deg F that the heat pump is pretty much useless. When temps are going to be below 38 deg. F I stop using the heat pump and turn on the fireplace and the furnace.
You have a Penguin Lo Profile. There are gaskets between the top side coils and the top plastic cover. Those gaskets make sure all the air flows correctly thru the condenser. IF those gaskets are missing or incorrectly installed, then the compressor will indeed overload and trip the breaker in Heat Pump Mode. Will not do it in COOL mode. So, you need to contac Dometic and ask them about the unpublished TSB about this concern. Doug
See Bulletin A30-7A
Note: If the foam is installed on
the shroud and you are getting high
amps/breakers tripping, remove
foam and call Warranty Department
to order foam kit part#
3312081.000. Install Foam Kit on
Unit – NOT the shroud.
It is okay to have foam
on shroud – only if
experiencing problems
does it need to be
replaced
• Symptom – High
Amps, Tripping
Breakers
• The foam makes an air
tight seal which forces
the air through the
condenser – Air will
travel the path of least
resistance if foam is
missing, compressed or
installed improperly.
