Please help. My Goodman furnace is leaking from the little condensator pump. The pump will not shut off. Is there anything I can do until a technician comes out 5 days from now? The furnace works.

You either have a bad pump or a restriction in the discharge line from the pump. Unplug the pump, disconnect the hose & try to blow out the hose. You can get 3/8" hose at any home center.
Put a new piece of hose on the pump & put the discharge end into a bucket. Plug the pump in & see what happens. If the pump won't pump out the water in it, the pump is bad. Replacements are available at most home centers.
