Is it safe to clear Arthur Martin error code High Temp Alarm by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Arthur Martin code High Temp Alarm persists, the physical component causing Recent loading of warm food, a prolonged door opening, a power failure, or a fault in the cooling system. must be inspected or replaced.

How do I test electrical resistance for Arthur Martin code High Temp Alarm using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero.

What safety protocol must be followed before servicing Arthur Martin code High Temp Alarm?

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.

1. Pre-Intervention Electrical Safety Protocols

!Refrigeration Safety Protocol: Disconnect mains power before unclipping compressor terminal covers.
!Flammable Refrigerant Warning: R600a (isobutane) is flammable. Never puncture cooling tubes or use open flame.
!High Surface Temperature: Compressor shell can exceed 80°C during normal operation. Allow to cool before inspection.

3. Preliminary Mechanical & Visual Checks

Listen for compressor startup attempts: repetitive clicking every 60 seconds indicates locked rotor or failed PTC relay.
Inspect evaporator coil for thick solid frost buildup, signaling defrost heater, sensor, or timer failure.
Clean condenser coils and check cooling fan motor for free rotation and dust accumulation.

Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
