Met with Jack and proceeded to perform a PTU on a Amana propane fired heap pump / furnace. Opened up the cabinet and inspected the following items: all electrical wiring with their connections, the pressure switches, rollout switches,flame sensor, igniter, fresh air intake, exhaust with the concentric piping, the filter , the blower with circuit boards and Ecm motor, capacitor, etc. etc. etc. I asked jack to turn up the thermostat and I observed the unit go through its full firing sequence of operation. All is good, no issues to report at this time.
