I have a contactor switch in my heat pump with the wires connected on each side which is no problem-just switch them exactly to the new switch-the problem is the old switch has two wires connected to the bottom--the new switch has one contact on the front and one on the back-do I just pull the wires on the old switch and hook one in the front and one in the back on the new switch-I think the wires go to the coil-have no wire diagram because the unit is over 8 years old and worn out so you cant read it-it was 19 degrees here in sc for 3 days in a row and it seems like the heat pump never shut off-its a heil split unit-outside and in the attic the contactor switch is 1p 25a 24v-model#HHP230AKC3 on the outside unit

At 19* outside the heat pump will run forever unless the back up heat helps it out. What the brand and model number of the furnace.

BITTERS--the brand is heil-the model#HHP230AKC3--about 9 years old

That's the heat pump number, what about the furnace? Does the furnace have electric or gas back up ?

It must be electric-the only gas I have is to the fireplace
