We have a G23 Series Unit that is having problems at the moment. The fan won't cycle properly. Once it comes on, it won't shut off. Have had someone service it and they installed a new blower control board, but that has made no difference.
Yesterday we ran it through 5 cycles and the fan never shut off. This morning another cycle and the fan did turn off. Suggestions?? Would like a little advice before I call them back for another service call.
