The Wacker Neuson is a genuine OEM Temperature Switch designed for the HI750GM, HI900DGM, and CUB700GM series indirect-fired air heaters. Sourced directly from Wacker Neuson, this part carries the exact electrical rating and calibration required by these diesel-powered climate units. It is confirmed to fit multiple HI750GM and HI900DGM configurations, including surge brake and mobile genset variants, as well as the CUB700GM mobile indirect fired air heater. When you need a direct, verified replacement that restores correct thermal control, part number is the right choice.
Key Features
- Correct Thermal Trip Point: — Genuine OEM calibration ensures the switch opens and closes at the precise temperature thresholds these indirect-fired heaters require for safe, controlled operation.
- Direct Drop-In Replacement: — Matches the original connector, thread specification, and mounting position, so the 5000182026 installs into the existing heater housing without modification.
- Broad HI-Series Fitment: — Verified for HI750GM, HI750GM HD Mobile, HI900DGM, and CUB700GM heater variants, covering standard, surge brake, and genset-equipped configurations.
- Protects the Heat Exchanger: — A correctly functioning temperature switch prevents the burner from running beyond safe limits, guarding the heat exchanger against thermal stress and premature failure.
- Fuel System Safety Compliance: — In indirect-fired heaters, the temperature switch is a primary over-temperature safety device; using a correctly rated OEM part maintains the protective cut-off function the heater relies on.
The temperature switch monitors the operating temperature inside the indirect-fired air heater and signals the control circuit to shut down or restrict the burner when temperatures exceed a safe threshold. This protects the heat exchanger, combustion chamber, and downstream components from overheating damage, and ensures the heater cycles correctly to maintain a consistent output temperature. When the switch fails or drifts out of calibration, the heater may shut down unexpectedly, fail to reach target temperature, or — in a worst case — allow the unit to run beyond safe limits, making prompt replacement with the correct-specification part essential.
