Description
The Dinosaur FAN 50 Plus Pins combines ignition and blower control for compatible 12-volt RV furnaces. It replaces selected Suburban and Atwood/HydroFlame fan-control boards and can also add fan-control operation to certain older furnaces when the required wiring conversion is performed.
Fitment & Compatibility
Dinosaur lists these original-equipment fan-control board numbers:
- Suburban: 232613 and 232614
- Atwood / HydroFlame: 37875 and 33488
- Earlier Dinosaur controls: Fan 50 Plus and UIB Fan Control boards, with suitable furnace wiring
This board uses a standard six-position edge connector or newer six-pin header connection. Verify the original board, connector, thermostat wiring and furnace fan-control circuit before ordering.
Features & Configuration
- Manufacturer model: FAN 50 Plus Pins; 12 VDC furnace systems only
- Replacement setup: Keep the mode-selection jumper across both pins for the listed OEM fan-control board applications; the supplied red/orange conversion wires are not used
- Older-furnace upgrade: A different jumper position and the supplied red/orange wiring are required when converting a furnace with a conventional ignitor and time-delay relay
- Ignition sequence: Three ignition attempts; stops unnecessary blower operation after failed ignition, then makes a further retry cycle after approximately one hour
- Diagnostics: Indicator LED and local flame sensing
- Exclusion: Not for DuoTherm 900/9000 furnaces using a ground-switched thermostat unless correctly rewired by a qualified technician
- Warranty: Three-year limited manufacturer board warranty
The fan-control feature must remain active. Incorrect connections or gas-system servicing present hazards; use a qualified RV furnace technician.
