Atwood heat pump problems

Bought new FR3 with an attwood heat pump ac. The temperature on the thermostat jumps 10 degrees in 2 minutes and shuts the unit off. The fan then comes on every 2 minutes then compressor starts again for only 2 to 3 minutes. The coach temp is 68 but the unit thinks it's 78. Attwood said this is normal so won't pay for troubleshooting under warranty. Anyone else have this issue?

pop the air filter off the grill and see if there is a divider between the return air and intake air or not. there should be a partition between grill and upper unit, half way back. thought maybe the sensor for temp may be on the upper board and not the thermostat.
