⚠️ Common Symptoms of a Failing Primary Control
If you notice these issues, your control may need replacement:
-
🔸 Burner fails to start or locks out repeatedly
-
🔸 No spark during ignition trial period
-
🔸 Flame detected but burner shuts down early
-
🔸 Alarm or reset light constantly illuminated
-
🔸 Inconsistent ignition or delayed startup
-
🔸 Ignitor remains energized continuously (no cutoff)
❓ (FAQ) Frequently Asked Questions
Q: What’s the difference between interrupted and intermittent ignition?
A: Interrupted ignition de-energizes the ignitor after the flame is established, extending the ignitor’s lifespan.
Q: Can I use this control on any 120V oil burner?
A: Yes — it’s compatible with most standard 120V oil burners equipped with a cad cell flame sensor.
Q: Does this unit recycle after flame failure?
A: Yes, it automatically recycles after a flame failure for safer restart operation.
Q: What does the alarm contact do?
A: The 24V alarm contact can trigger a remote alarm or system monitor in the event of lockout.
