Amana Refrigerator Error Codes — Complete Error Code Diagnosis Guide

Amana refrigerators use short two-letter alerts rather than numbered faults, and four of them are covered here. PO is a power-outage flag: the unit is telling you it lost supply and warmed while nobody was watching. HI and LO are temperature alerts in opposite directions — a compartment too warm after a door was left open or a cooling fault developed, and a freezer running colder than its setpoint on a drifting thermistor. CF is a communication failure, where the main board and the display board have stopped talking through the harness that joins them.

The order these are read in matters, because two of the four are history rather than a fault. PO and HI can both describe an event that has already ended, so each guide starts by asking whether the condition is still true: is the compartment recovering, or still warm hours later? Only then does it move to the parts a persistent alert implicates — thermistors that drift, a harness pin that has corroded, a display board that answers nothing. CF is worked at the connectors first, since a loose plug and a dead board present identically.

A refrigerator hides its most restricted repair behind an ordinary-looking panel. Anything that opens the sealed refrigerant circuit is regulated work, and no alert code on this list justifies it — none of the four is a sealed-system diagnosis. Thermistors, harnesses and boards are serviceable; a compressor that will not start is a different conversation. If food has been above temperature for an unknown span, treat the alert as an alert.
