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
gfci the switch is not the pump is the only thing on the gfci they replaced
the pump and it still trips any thoughts?


Check the wiring of the GFCI. Those combination devices can be a little tricky.
