Heavy-duty solid-state timing circuit resists electrical noise and temperature-induced drift

This specific 30-degree differential prevents rapid cycling while ensuring the furnace operates within safe thermal parameters

or the burner shutting down shortly after startup due to a lost vacuum signal

Repeated tripping is usually indicative of restricted airflow

Sterling HVAC 11J38R06891-001 Ignitor Els PW 17895 Heavy-duty solid-state timing circuit resistsThe Sterling HVAC 11J38R06891 001 Ignitor is a critical direct spark ignition component designed for reliable combustion in high demand heating environments. Engineered specifically for use in Sterling TF, GF, and XF gas heaters, this spark ignitor probe ensures immediate fuel ignition to prevent gas buildup and short cycling. This part is a direct factory replacement and is technically identical to the J38R06891 001 model, featuring an angled probe
