Resideo R8184G4009/U Protectorelay® Oil Burner Control with 45 Second Safety Timing

The R8184G4009 is an oil burner primary control from Resideo (Honeywell Home), 45 seconds safety timing.

The primary control runs the burner sequence and decides when to stop. It calls for ignition, opens the oil, watches the cad cell, and if no flame appears within the safety timing it shuts down and locks out. That timing is the whole safety case: it bounds how much oil can reach a cold chamber before the control gives up.

Safety timing here is 45 seconds. Match it to what the appliance was designed around — the timing is not a preference, it is part of the burner’s listing.

Protectorelay is the electromechanical family. It has outlived several generations of electronics on oil burners because there is very little in it to drift, and a technician who has never seen this exact model still knows how it behaves.

A primary that keeps locking out is usually not the primary. Change the cad cell first, then check that it is aimed at the flame.
