How do I know if my defrost heater needs to be replaced?

Common signs include excessive frost buildup, temperature fluctuations, or ice covering the evaporator coil. If your system isn’t defrosting properly or is running continuously, a failed defrost heater may be the cause.

Are all defrost heaters the same size and voltage?

No—defrost heaters come in a variety of lengths, wattages, and voltages depending on the equipment. Always verify your system’s specifications or OEM part number before ordering a replacement.

How long do defrost heaters typically last?

Service life varies depending on usage, environment, and equipment, but most defrost heaters last several years under normal conditions. Routine maintenance and timely replacement help prevent system issues.
