Wacker Neuson 1000027179 Timer Contact

The Wacker Neuson Timer Contact is a genuine OEM component designed for the TH627 indirect-fired air heater. As a factory-sourced part, the is manufactured to the exact specification of the original, ensuring proper integration with the heater's ignition and control circuit. Sourcing the correct timer contact by confirmed part number is critical on climate equipment where control timing directly affects safe, consistent operation.

Key Features

• Genuine OEM Electrical Precision — Factory-manufactured to the original contact rating and switching specification, so the timer circuit opens and closes at exactly the right point in the heater cycle.
• Direct-Fit Replacement — Engineered to drop into the existing timer assembly of the TH627, connecting to original terminals without modification to wiring or mounting hardware.
• Confirmed Fitment — Verified against Wacker Neuson spare parts list 418-02 for the TH627 indirect-fired air heater series.
• Consistent Heat Cycle Control — A correctly functioning timer contact keeps the burner firing on schedule; a worn or pitted contact causes erratic ignition, incomplete burn cycles, or heater shutdown.
• Fuel System Safety Relevance — In a fuel-fired heater, proper timer contact function is essential to ensure the burner ignites and shuts off as intended, preventing uncontrolled fuel delivery or nuisance lockouts.

The timer contact is an electrical switching component within the heater's control circuit that governs when the burner ignites and when it cuts out. On indirect-fired air heaters like the TH627, precise timing is essential to achieving clean ignition, maintaining target output temperature, and executing a safe shutdown sequence. When the contact surface wears, corrodes, or fails to close cleanly, the heater may fail to start, cycle erratically, or trigger a safety lockout — interrupting heat output on the jobsite.
