Bosch E136

Bosch error code E136 indicates: Inverter temperature (IGBT) is three times higher.

The primary root cause for Bosch code E136 is: Inverter overheating (T thermistor > 75°C); Insufficient cooling of the device; Refrigeration fan within the country; Magnetron fan without function; Ambient temperature > 30°C; Duration of professional use; Control module failure.

To resolve error code E136: Consult program test 12 “inverter overheating”; Mount the appliance seal the installation / assembly instructions; Refrigeration fan changer; Magnetron fan changer; Advise the client, reduce the ambient temperature; Extend the cooling phases between uses; Change control module

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E136 persists, the physical component causing Inverter overheating (T thermistor > 75°C); Insufficient cooling of the device; Refrigeration fan within the country; Magnetron fan without function; Ambient temperature > 30°C; Duration of professional use; Control module failure must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
