The Wacker Neuson Sarkler Relay is a genuine OEM component designed for the TH627 indirect-fired air heater. As a direct factory replacement, this relay is sourced from Wacker Neuson and matches the original specification fitted at the time of manufacture. Confirmed fitment covers the TH627 series, making part verification straightforward before you order.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact switching ratings and coil characteristics of the original relay, ensuring correct ignition sequencing in the TH627 heater control circuit.
- Direct Drop-In Replacement — Matches the original connector and mounting configuration, allowing straightforward installation without adapting wiring or brackets.
- Confirmed TH627 Fitment — Verified against the TH627 indirect-fired air heater spare parts list, so you can order with confidence.
- Restores Reliable Ignition Control — A functioning sarkler relay is critical to the heater's burner ignition cycle; a failed unit will prevent the heater from firing or cause intermittent ignition faults.
- Fuel System Safety Compliance — As part of the burner control circuit, using the correct OEM-specified relay helps maintain the integrity of the heater's fuel ignition safety sequence.
The sarkler relay is an electromechanical switching component within the burner control circuit of the TH627 indirect-fired air heater. It receives a signal from the heater's control board and switches power to the ignition or fuel system at the correct point in the startup sequence. When this relay fails, the heater may not ignite, may cycle on and off erratically, or may shut down entirely — leaving the unit unable to deliver heat output on the jobsite.
