About this product

Product Information

Run a furnace and other HVAC systems continuously and smoothly with the Universal Integrated Ignition Fan Control (50A55-843). The 50A55 series unit is designed and constructed by White-Rodgers. It's a multi-functional controller that monitors the integrity of motors and maintains motor operational efficiency. The White Rodgers unit has a well-engineered design that helps to facilitate easy installation in a furnace and other HVAC units. Technicians will be pleased by the reliable heat and air controls enabled by the Universal Integrated Ignition Fan Control. The White-Rodgers control unit measures 8 by 5 by 2.5 inches and weighs 12.8 ounces. Its frame is constructed of plastic, which makes the unit both lightweight and durable. It is designed for a furnace with a silicon carbide ignitor as well as other HVAC systems. The board utilizes a microprocessor that acts as a central controller. The White-Rodgers modules can operate various brands of furnace, ventilation, air conditioning, and humidifier units via provided terminals. The board design allows the microprocessor to monitor systems so that environments remain stable in varying climates and seasons. It has a designated input voltage of 25 volts AC at 50/60 Hz and a maximum current of 25 VAC: 0.45 AMP. The control unit’s valve relay runs at 1.5 AMP. The ignitor relay runs at 6 AMP 120 VAC 50/60 hertz. Its 25-watt power supply is connected via a 0.25-inch Quick Connect 12-pin interface. With these specifications, the control module utilizes power efficiently. It is designed to operate between a temperature range of -40 to 175 degrees Fahrenheit in a furnace or air conditioner. It can also tolerate a humidity range of between 5 and 93 percent. As such, the unit can be relied on to operate as expected in hot, cold, and dry conditions. For installation and troubleshooting motor failures, a flash code diagnostic system is equipped on the control board. This allows technicians and homeowners to readily identify issues with a blower or other components when installing the replacement module. Different continuous and flashing light indications can provide information on external and internal operations. The surface of the unit features an ordered guide on what these different sequences mean. This helps to identify component shorts or other wiring issues that need to be addressed and corrected. The diagnostic system also works to protect technicians and homeowners by providing a warning mechanism. This mechanism can alert users to electrical malfunctions that necessitate turning off the gas supply of a furnace. In addition, the fuse arrangement is designed to safeguard low-voltage system transformers. The fuse switch assists in ensuring that motors are protected from low-voltage faults and short-circuiting. This White-Rodgers Ignition Control unit also comes with a part cross-reference chart. Users can check whether the 50A55-843 replaces a previous model on a particular furnace or air conditioner. It is compatible with a variety of systems made by manufacturers like Trane and Honeywell. Furthermore, the factory replacement module has an array of customizable features. These include adjustments to the inducer blower motor relay and a DIP switch for delays in on-and-off sequences. Connections are easily labeled for hassle-free switching by technicians. Securing the unit to a furnace is also made easy by the provided mounting hole template.

    I never received the item I paid for. The seller didn’t ship the package, provided no updates, and ignored my messages. Completely unprofessional – avoid at all costs.

    This is completely on me but in that case this buyer purposely purchased my cheapest item in order to screw me on feedback because I left a review on an item that this seller canceled. They never messaged me about this item not being sent in fact they never answered my messages when I asked to resolve the problem I had on my buying end of his items. Buy scum bags as this user will get what they deserve judgement day. I’ll own this feedback for sure

    Replacement for 50A50-571 for Trane applications

    I have two Trane XE1200 air conditioning units circa 1998 installed originally with the 50A50-571 control boards. One of the control boards became defective during 2008 winter and furnace would not start on call for heat. The second one went bad after few years this 2019 spring when call for cooling did not fire up the circulator fan. I found this one was replacement for the discontinued board. It is smaller size than the original board and connectors have been moved around. The manufacturer has provided few jumper cables to extend original wiring in case they are out of reach due to change in position. I had to use these cables as the original would not reach the new positions. For Trane application, one has to also use the supplied jumper cable to connect the terminals for the roll out ...

    Critical item for your comfort, easy to replace.

    This Furnace control unit was used on many older a/c-furnaces and based on my experience, they last around 10 years, so the cost per year is pretty reasonable. This is my third one (been here since 1992) and while it 's annoying to have your furnace or a/c go out (just when you need it) knowing it's a weak spot and can be fixed easily makes me feel a little better. As for a DIY project, it's a good idea to take photos of the wire placements so if you lose track during the replacement, you can go back to the photo.

    Heating problem solved, easy installed

    Replaced my white rodgers 50A50-241 with 50A55-843 with no problems it was exact wire plugs. Had to drill four new holes for new Module but that was it. My old module would make my blower run by itself with everything on the off position and heater will run only for a short time then cut off and blower would continue on had to turn off at the breaker. Very satisfied with product would recomend.

    Quick Fix

    My control board led wasn’t blinking even though it had power. I bought this and installed it by moving one wire at a time. When I was done, I turned on the power and the furnace lit instantly. This was an exact match and the job couldn’t have been easier. Highly recommended.

    Replace it with the Universal Control Module

    Instruction is easy to follow for installation and setting up the dip switch. You need to mount the module to a difference location if you are not going to use the jumper leads that come with it. Ran fine (I'm in HVAC field for a living).
