The defrost heater is mounted near the evaporator coils and periodically activates during the dishwasher's defrost cycle to melt frost buildup that accumulates on the coils. Without functioning defrost, frost continues to build up on the evaporator until it blocks airflow — causing the refrigerator or freezer to lose cooling efficiency, run continuously, and ultimately fail to maintain set temperatures.\u003c\/p\u003e\n\u003cp\u003eAs a Genuine OEM part manufactured by Frigidaire\/Electrolux to factory specifications, the 5304524953 directly replaces 5304523833, AP6997296, PS16227227, and 4975045. Tip: when replacing the defrost heater, it's a good time to also inspect or replace the paired defrost thermostat and defrost timer\/control board — these three components form the defrost system and often fail in sequence. Addressing them together saves a future repair.

The defrost heater is mounted near the evaporator coils, behind the rear interior access panel of the freezer compartment. Remove all freezer shelves, drawers, and the ice maker (if equipped) to clear access. If there's a heavy ice sheet covering the back wall, allow the freezer to thaw completely or carefully manually defrost the coils before continuing — never break ice off the coils, as this damages the aluminum fins. Once the area is clear, remove the screws securing the rear access panel and lift it away to expose the evaporator coils and the defrost heater. Photograph the wire connections and heater orientation before disconnecting. Disconnect the wire harness connectors from the old heater, release the heater from its mounting clips or brackets, and lift it out. Install the new 5304524953 heater in the same position, ensuring it's properly seated in the mounting brackets, and reconnect the wire harness. While the panel is open, inspect the defrost thermostat for damage — if it's brittle, discolored, or shows visible defects, this is the ideal time to replace it as well. Reinstall the rear access panel, shelves, drawers, and ice maker. Plug the refrigerator back in and allow several hours for the unit to return to its set temperature before reloading with food. Tools needed: Phillips screwdriver, 1\/4\" nut driver, work gloves, safety glasses.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-card\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eHow do I know if the defrost heater has failed?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eThe most reliable sign is heavy frost or ice buildup on the evaporator coils behind the freezer back panel — when the heater can't melt the frost as designed, ice accumulates until it blocks airflow and cooling efficiency drops. You may also notice the freezer or fresh food section running warm, the compressor running continuously, or food spoiling faster than normal. To confirm with the refrigerator unplugged: remove the rear freezer access panel, disconnect the heater's wire harness, and test the heater's terminals with a multimeter set to continuity mode. A working heater shows continuity (low resistance); a failed heater shows an open circuit (infinite resistance). If you measure no continuity, the heater has burned out and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eShould I replace the defrost thermostat and timer at the same time?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eYes, it's strongly recommended. The defrost heater, defrost thermostat, and defrost timer\/control board work together as a system — the timer (or control board on newer models) initiates the defrost cycle, the thermostat monitors the temperature at the coils and terminates the cycle when the coils are above freezing, and the heater provides the heat that melts the frost. When one component fails, the others have typically experienced similar age and stress, and a near-term failure of another defrost component is common. Since the rear access panel must already be off and the components are right next to each other, replacing all three in a single session prevents a repeat repair down the road.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eShould I manually defrost my freezer before installing the new heater?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eIf there's significant ice buildup on the evaporator coils or rear wall, yes — you need to clear it before installing the new heater. Leave the freezer empty and unplugged with the door open for 12–24 hours (or longer for heavy ice) to let everything thaw naturally. Place towels at the base to catch melt water. Do NOT chip or pry ice off the evaporator coils with any tool — the aluminum fins damage easily and a damaged coil is a far more expensive repair. Once everything is fully thawed and dried, you can proceed with the heater replacement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eMy refrigerator\/freezer has multiple defrost heater-related part numbers — which one do I need?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eFrigidaire\/Electrolux uses different defrost heater part numbers across different generations and models.
