I have an older Nordyne heat pump that has been icing over real bad recently. I checked the defrost board and the defrost cycle will come on when tested but I do not hear it turning on on its own. Upon inspection the coil temperature sensor is not attached to the coil anymore. It is just dangling from its wire down inside the unit. I believe this is my problem. My question is: Where on the coil does this sensor need to be installed and does it matter how close to the original location it is?
