Dinosaur Electronics 24V AC 3-Year Warranty UIB24VAC 24V AC Park Model Furnace Replacement Ignitor Board (Part 41-0050)

When your park model or RV furnace stops lighting, the ignitor board is often the culprit. The Dinosaur Electronics UIB24VAC is a direct-replacement ignitor control board for furnaces that operate on 24-volt AC power -- including Duo-Therm, Hydro-Flame, and Suburban park model units. It is a drop-in upgrade with onboard diagnostics, overcurrent protection, and a 3-year manufacturer warranty that outpaces most OEM replacements.

Reliable Ignition Control for 24V AC Furnace Systems

Park model furnaces and some older RV furnaces use 24-volt AC ignitor boards rather than the 12V DC boards found in standard travel trailers and motorhomes. Finding a quality replacement for these units can be difficult. Dinosaur Electronics has specialized in RV furnace board replacements for decades, and the UIB24VAC is purpose-built for this specific application.

This board installs in the same footprint as the original, connects to the same wiring harness, and adds genuine improvements: a 3-try microcontrolled ignition sequence, onboard diagnostic LED indicators, and a built-in fuse that protects the 24V circuitry from short circuit damage -- a common failure point on unprotected OEM boards.

3-Try Ignition Sequence

Microcontrolled board attempts ignition up to 3 times before locking out, improving cold-weather and low-gas-pressure starts.

Diagnostic LED Indicators

Green LED confirms power to the board. Red LED indicates power to the gas valve. Simplifies troubleshooting without a multimeter.

Onboard Fuse and Surge Protection

Built-in fuse protects 24V circuits from short circuit damage. Surge protection reduces risk of board failure from power spikes.

3-Year Manufacturer Warranty

Limited 3-year warranty from Dinosaur Electronics -- significantly longer coverage than most OEM furnace boards.

Who This Board Fits

This ignitor board is designed for furnaces that use a 24-volt AC ignitor board. That includes many Duo-Therm, Hydro-Flame, and Suburban furnaces installed in park model homes and some older RV applications. Before ordering, confirm that your existing board is labeled for 24 VAC operation -- this board will NOT work in standard 12V DC RV furnace applications.

How to confirm compatibility: Check the label on your existing ignitor board. If it specifies 24 VAC (not 12VDC), this replacement is the correct voltage class. Cross-reference Dinosaur part number 41-0050 or board model UIB24VAC with your furnace model for confirmation.

LED Diagnostic Guide

The two onboard LEDs make field diagnosis much faster than probing with a meter:

  • Green LED on: Board is receiving 24V AC power. Wiring from transformer to board is good.
  • Red LED on: Board is sending power to the gas valve. If the red LED is on but the furnace is not lighting, suspect the gas valve, igniter electrode, or flame sensor.
  • No LEDs: No power reaching the board -- check thermostat wiring, transformer output, and fuse on the board.
Upgrade Benefit: OEM park model ignitor boards frequently lack onboard fuse protection. A short on the 24V circuit can destroy an unprotected board instantly. The UIB24VAC includes this protection as a standard feature, not an add-on.

Installation Overview

Replacement follows a straightforward process for anyone comfortable with basic furnace service:

  • Disconnect power and gas before beginning any work.
  • Photograph the existing wiring connections on the old board before removal.
  • Remove the old board and transfer all wiring connectors to the matching terminals on the UIB24VAC.
  • Secure the board using the existing mounting hardware -- board dimensions are 3-3/7" x 5-1/10" (approximately 3.43" x 5.1").
  • Restore power and test ignition sequence through the thermostat.
Maintenance Tip: While the furnace panel is open, inspect the igniter electrode gap and clean the flame sensor rod with fine steel wool. A contaminated flame sensor is one of the most common causes of ignition lockout and costs nothing to address during a board swap.
Also from Dinosaur Electronics: If you are unsure whether your furnace uses a 24V AC or 12V DC board, Dinosaur Electronics makes ignitor boards for both voltage classes across a wide range of furnace brands. Confirm your board voltage before ordering.

Important Information -- Read Before Ordering and Installing
  • This board is designed for 24-volt AC furnace applications only. Installing it in a 12V DC furnace system will not work and may damage the board or furnace components.
  • Always disconnect both electrical power and the gas supply before removing or installing any furnace control board.
  • Verify your existing board is labeled 24 VAC before purchasing. The voltage designation is typically printed on the board label or the furnace wiring diagram.
  • This listing is for the ignitor control board only. Igniter electrodes, flame sensors, gas valves, and thermostats are not included.
  • If the replacement board does not resolve the furnace fault, inspect the igniter electrode, flame sensor, gas valve, and thermostat wiring before concluding the board is defective.
  • Furnace service involving gas components should only be performed by qualified individuals. Improper installation can result in gas leaks or fire.
