Almost every freezer that ices up has a defrost problem behind it, and the defrost system has several parts that fail in different ways. JRC diagnoses and repairs defrost faults across Paron, AR.
Electric defrost heaters open circuit and stop producing heat while everything else keeps running. Termination thermostats drift and cut the cycle short before the coil clears. Mechanical timers seize or lose their advance. Drain lines freeze solid, so meltwater backs up and refreezes on the coil, which looks identical to a heater failure until you check. We test each element rather than replacing the timer and hoping, and we heat trace drain lines where the run passes through freezer space.
