Arrived to find unit â€œoffâ€ I engaged unit to run in heating mode, it cam on per request and ran without issue. After talking with homeowner about alleged problem she stated she saw lights flashing in unit while unit wasnâ€™t running. I informed her that that indicates â€œnormal operationâ€ she also stated unit hasnâ€™t ever lost stat satisfaction call seems to be misunderstood operation. I did recall faults and unit did have 2 flashes siting to check pressure switch wires, I gave thorough evaluation of pressure switches, drain and vent and couldnâ€™t conclude any issues with unit. All checks are good, I did treat drainage with dawn
