Customer Question

Hi,
I have a White-Rodgers 50A50-471 furnace controller. Heat works fine, blower motor works when AC setting is on but the compressor will not start. The compressor doesn't supply the 24v reguired. The cooling connections are fine but I do not get 24v on the yellow side to start the compressor. Does the controller provide the 24v or do i need a tramsformer installed.
