Haier Er07

Haier error code ER07 indicates: Haier Series 4 / 6 Chef@Home & I-Message Connected Oven: Food meat probe circuit fault Er07; internal core thermometer probe reads short-circuited or out-of-scale temperature..

The primary root cause for Haier code ER07 is: On Haier ovens featuring Chef@Home multi-zone convection system, high-precision cavity thermal probe, and I-Message electronic controller: Liquid grease ingress inside meat probe jack socket on cavity wall, punctured probe silicone cord, or shorted connector..

To resolve error code ER07: Unplug meat probe from wall jack. Clean socket contact pins with isopropyl alcohol. Measure probe resistance with multimeter (~10 kΩ or ~1000 Ω depending on type). Touch Settings menu on display, select System Reset, hold confirmation checkmark for 5 seconds, or power cycle breaker for 60 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code ER07 persists, the physical component causing On Haier ovens featuring Chef@Home multi-zone convection system, high-precision cavity thermal probe, and I-Message electronic controller: Liquid grease ingress inside meat probe jack socket on cavity wall, punctured probe silicone cord, or shorted connector. 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.
