I have a new furnace and a condensate pump the code requires the pump to be on
a gfci so they installed a combination switch receptacle the receptacle is

the pump and it still trips any thoughts?

Get a different pump, but don't be surprised if it still trips.

Keep replacing the pump until the tripping stops? :-\
No, iI'd try a "different" pump - not just another identical unit. If
it trips too ----, I'd just get rid of the GFCI after it has passed
inspection. The pumps virtually ALL have minor electrical leakage in
real life operation. The electrics are NOT hermetically sealed, and
they are damp.Not only damp, but the condensate is also
acidic/corrosive. Requiring a GFCI on the pump is ludicrous. Just
ground it well and it is not a safety hazard.

I have a Little Giant condensate pump on a GFCI receptacle, which
is required by code, because it's in a basement. No tripping, ever.
The issue with the receptacle and safety hazard are
that something other than the pump can be plugged in. Probably not
likely, but a homeowner with a flooded basement could be using a
shop vac and plug it in.
