GE ER03

GE error code ER03 indicates: GE Profile Touch Control & Precision Induction Cooktop: Permanent touch key activation alarm ER03; liquid spill or cookware resting continuously on sensor controls..

The primary root cause for GE code ER03 is: On GE cooktops utilizing Profile Touch Control precision induction generators, pan presence detection coils, and digital slider interface: Heavy liquid overflow across touch buttons, conductive sauce splatter, or pan overhang onto glass touch zone..

To resolve error code ER03: Remove all pots and utensils from glass. Sponge up all liquids and dry touch area thoroughly with a clean microfiber cloth. Remove all pots, disconnect cooktop at circuit breaker panel for 60 seconds, reconnect and hold Lock Control pad for 3 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if GE code ER03 persists, the physical component causing On GE cooktops utilizing Profile Touch Control precision induction generators, pan presence detection coils, and digital slider interface: Heavy liquid overflow across touch buttons, conductive sauce splatter, or pan overhang onto glass touch zone. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
