Its really quite simple to repair.
First you will need a belt sander. Take the little spring thingy out
of the contactor. Now remove the top portion of the contacts. Glue it
to a piece of wood with Gorilla Glue. Now run the belt sander with #80
grit paper over the contacts for about 5 minutes
Now for the lower contacts. For this you will need some muratic acid.
Pour about a cup over the lower contacts. Let this sit for about 1/2
hr. Now be sure and rinse it all off with a hose.
Finally, reassemble and set the heat pump thermostat back to heat.
Note: This will all work a lot faster if you make sure the contactor
has power applied to it at all times.
Bring some marshmallows.
