Understanding the problem
Ice that returns soon after a thaw may indicate a defrost, drainage, airflow, or moisture-entry problem. Equipment uses different defrost methods, so the correct sequence depends on the model.
What our service assessment covers
We review the intended defrost sequence and inspect applicable sensors, timers, heaters, termination controls, fan delays, and drains. The diagnosis also considers door use and room humidity.
Before you schedule
Note when frost returns after defrost and which coil areas are affected. Share error codes and the manufacturer’s model number before the visit.
