Electrolux Dryer Error Code 0x62

Error code 0x62 on an Electrolux dryer indicates a Heater Short Circuit Error. This fault is triggered when the main control board detects an abnormal condition in the heater relay circuit, specifically when the relay is stuck in either the open or closed position, or when the heater element itself has failed. The heater relay is responsible for switching power to the heating element on and off under command from the main board. When this relay fails to open or close as expected, the board cannot confirm proper circuit behavior and throws the 0x62 fault to prevent unsafe operation.

The primary diagnostic step for this error is to measure resistance between connector terminals J3-1 and J4-2 on the main board. The expected resistance is 100 ohms, with an acceptable tolerance of plus or minus 5 percent, meaning readings should fall between 95 and 105 ohms. A reading significantly outside this range points to a defect in the heater element itself. An open circuit reading suggests a broken element, while a very low resistance or near-zero reading indicates a shorted heater coil. Wiring continuity between these connector points should also be checked for damaged insulation, corroded terminals, or loose connections before condemning the heater or relay.

Because this fault encompasses three possible failure points, including the relay on the main board, the heater element, and the interconnecting wiring, a systematic approach is essential. If wiring checks out and the resistance at J3-1 to J4-2 is within specification, the fault likely resides in the relay circuit on the main board itself. A stuck-closed relay is a potential fire hazard because it can allow continuous power to the heater regardless of thermostat input, making prompt diagnosis critical.
