What hi PSI
actually means.
On True's 15-inch clear ice models, hi alternating with PSI means refrigeration pressure is too high. True's first step is cleaning the condenser coil, then pressing the power button twice to reset; a coil clogged with dust or blocked airflow keeps heat in the system.

What to do when hi PSI shows on the ice makerKind of codeFans and airflow
The fan that moves cold air to the ice maker stopped, slowed or froze in place. A door ice maker depends on that air, carried to the door through a duct, so when the fan quits the ice compartment warms and cubes melt and refreeze into clumps. Ice blocking the blades or the duct is ruled out before a motor is ordered.
Usually leads toDiagnostic visit
A visit that traces the water from the supply valve to the bin and back out through the drain, and names the one part that stopped the ice before anything is ordered.
Shows up asNo Ice Coming From the Ice Maker
The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally.
