Jumpered the bimetal thermostat and everything worked smoothly. Tried to clean contacts in thermostat with no luck, so ordered a replacement. At least it was cheaper than the contactor.

If unit worked before you tryed changing t-stat then its possible the t-stat wires are shorting each other out.take t-stat back off cut back wires a good 6 to 10 inches or if you dont have that much wire to play with just cut back as far as you can and make sure there is no bare wire touching each other ,then just to test unit to make sure its working ok twist yell.,red,green together this should bring both units on and should blow cold.if this works up to this point on the new stat read directions closely there might be a jumper wire in the stat that needs connected usually from y1 to w1 you would install a jumper wire .see if this helps if not write back i have 1 other solution.i hope this helps
