Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A malfunctioning AC controller might initially cause intermittent issues like the fan cutting out or temperature settings not responding. If left unaddressed, the HVAC system may cease to function entirely, leading to an uncomfortable and potentially unsafe working environment due to heat or fogged windows. This can impact operator productivity and safety.
Before disconnecting the old controller, ensure the excavator's battery is disconnected to prevent electrical shorts. When connecting the new unit, ensure all wiring harnesses are securely seated and properly routed to avoid pinching.
It is advisable to check the cabin air filter and the refrigerant charge level in the AC system when replacing the air conditioner controller.
