The Wacker Neuson Current Transformer is a genuine OEM component designed for the Arctic Bear HD indirect mobile air heater series, covering both the natural gas and diesel configurations. As a factory-sourced part, it matches the original electrical specifications of the unit it replaces, ensuring correct output and safe operation within the heater's control circuit. This transformer is the right choice when servicing Arctic Bear HD units that show signs of electrical fault, ignition failure, or inconsistent heating performance tied to the control system.
Key Features
- OEM-Matched Electrical Output — Wound and rated to the original specification, ensuring correct current sensing and signal accuracy within the heater's control circuit.
- Direct-Fit Replacement — Engineered to drop into the existing mounting position and connect to the original wiring harness without modification.
- Confirmed Arctic Bear HD Fitment — Compatible with both the Arctic Bear HD natural gas indirect mobile air heater (5000620199) and the Arctic Bear HD diesel mobile indirect air heater (5000620197).
- Critical to Ignition and Control Performance — A failed or out-of-spec current transformer can cause erratic ignition behavior, control board faults, or complete heater shutdown in cold-weather operations.
- Electrical Safety Compliance — Using the correct OEM-rated transformer maintains the integrity of the heater's electrical protection circuit, which is essential in fuel-fired heating equipment.
A current transformer monitors and converts the electrical current flowing through a circuit into a signal the control board can read and act on. In indirect-fired air heaters like the Arctic Bear HD, this signal is used to verify burner operation and protect the unit from fault conditions. When the transformer fails or drifts out of spec, the control system loses accurate feedback, which can result in ignition lockouts, false fault codes, or uncontrolled heater cycling — any of which will take a heater offline in conditions where consistent heat output is critical.
