15k AC unit heat pump squeek

[lickem66]

15k AC unit heat pump squeek started last night when the heat cycles on in our '16 FR3 28DS. Any tips on what to open up and lube? It does not squeek on just fan, only when heat kicks on.

My squeak was from the refrigerant lines that pass through from the outside to the inside to the condenser was rubbing the plastic housing. I move the condenser coil slightly to increase the space to the housing and eliminated the squeak.

Thanks. I'll take a look at that.

Is it just one squeak? Or is it a decrescendo type sound?

Nah. just more of one constant squeak. I have not had time lately to do more research on its origin though but it sounded like it was coming from the roof unit.
