I would check the therm also. About half the new ones we get arn't any good, but I think 180 is best. What temp. does the fan come on at. It may be set at 200. If so that is about right. If the system is all in good shape a 15 lb. cap should work good.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
