This unit belongs to a neighbor, I asked if there were any codes before she tried
to reset it by turning the breakers off for 15 min. (as instructed by a Whirlpool Rep on the phone) they told her to get a repair person if that didn't work. She didn't know what to do with the PF. She called me, I went over and cleared the PF. Everything seemed OK until I tried to adjust temp setting it would adjust down. I opened the unit and checked all of the connectors (unpluged, inspected, & reconnected) all appeared to be clean and making good contact. The touch pad ribbon was not firm in its plug but insured good contact in the control board & snapped in the plastic housing. I did not remove the control board from the panel but it looked OK from face side, no signs of component over heating.
Can a temperature sensor fail with out giving an error code?
