Wacker Neuson 1000027088 Time Relay

The Wacker Neuson Time Relay is a genuine OEM component designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this part meets the exact electrical specifications required for proper heater operation. If your TH627 is experiencing ignition timing faults or burner cycling issues, the time relay is a key component to inspect and replace.

Key Features

• Correct Switching Specification: — Genuine OEM construction ensures the relay operates at the precise timing intervals required by the TH627 burner control circuit.
• Direct OEM Replacement: — Drops into the existing control circuit of the TH627 without adaptation, matching original connector and mounting configuration.
• Confirmed Fitment: — Verified for the TH627 indirect-fired air heater (418-02 series), eliminating guesswork when sourcing electrical components.
• Burner Cycle Integrity: — A properly functioning time relay ensures the burner ignition and shutdown sequence runs on schedule, maintaining consistent heat output and fuel efficiency.
• Electrical Safety Compliance: — As a control-circuit component governing ignition timing, using the correct OEM relay helps ensure the heater operates within its designed safety parameters and avoids uncontrolled burner cycling.

The time relay is an electrical switching component that controls the timing of the burner ignition sequence in the TH627 indirect-fired air heater. It governs when the burner fires and how long specific stages of the startup and shutdown cycle run, coordinating with the broader control circuit to deliver safe, repeatable heat output. When the time relay fails or degrades, the heater may fail to ignite, cycle off prematurely, or exhibit erratic burner behavior — all of which interrupt heating operations and can trigger lockout conditions in the control system.
