Please see the 'Universal Cross Reference' link under 'Resources' on this product's page at: Hope this helps you. 2016-01-15 Yes the sku 50A55-843 is the suggested replacement for the 50A50-131. 2016-05-17 SupplyHouse Staff Does this replace the 50A55-120 in my Lennox-Aire Flo? I have read both yes and no in different places!

My existing board looks nothing like this but that doesn't mean it won't function the same way. Mine has WR printed on it, presumably White Rodgers. On the label it says 50A55-120 Lennox and several other numbers. Usual story.my AC contractor wants $530 but is trying to talk me in to sinking that in to a new system instead.

Steve 2015-06-26 The replacement for the 50A55-120, 56L85. 2015-07-07 Supplyhouse Staff I just installed the 50a55-843 as a replacement for a 50a55-110. Problem was the circulator blower would not run and believed it to be the relay on the control board. Replacement fixed the circulator blower but now the outside unit will not run although was previously running fine.Instructions say there is a second wire from the Y terminal to be connected to the 24 VAC hot side of the compressor contactor. I don't know how to make this connection as isn't the contactor on the outside unit? I assume this second connection isn't to a terminal on the control board. There is a dual fuel circuit board on the outside of the unit with colored wires from thermostat and to furnance and a set to the outside unit.

If I connect the yellow wire to one of the outside unit terminals which one.yellow, white, red, start, etc.nothing here is labeled to the hot side of the compressor contactor. I would appreciate any help Mark 2015-05-09 We do not have technicians on staff it would be best to contact White Rodgers tech support for those answers.

2015-05-11 Supplyhouse Staff Is this a direct replacement for Lennox 56L84 or 56L8401? Jesse 2015-04-28 No it is not, you should call us with the model & serial # of the unit to find the correct part. 2015-04-28 Supplyhouse Staff will this replace 50A50-571 Trane rodger white 2013-11-15 Hi, I used this universal module to replace my furnace module 50-A50-241. According to White Rogers data sheet it should also accommodate 50A50-571.

See the link below. You should be OK to use this one.

White-Rodgers White-Rodgers 50A50/50A51 Fault Diagnostics Pressure Switch Problem 50A51-495/-506/-507 Two Stage Variable-Speed Systems The induced draft motor will always be energized to high speed. The induced draft motor will be energized to low speed when the Control senses the 1st stage pressure switch contacts have closed. If the 1st stage pressure switch contacts open during a normal 1st stage heating cycle, the gas valve will be de-energized to remove the flame and the induced draft motor will be energized to high speed for 10 minutes.

If the 1st stage pressure switch contacts close during the 10 minute high speed purge, the Control will restart the ignition sequence. If the 1st stage pressure switch contacts remain closed after 10 minutes, the induced draft motor will be energized to low speed and a normal heating operation will continue. If the pressure switch contacts do not close after 10 minutes, the induced draft motor will be energized again to high speed for 10 minutes and the diagnostic LED will begin flashing 3 times to indicate a pressure switch problem. Recycling the induced draft motor will continue as long as a 1st stage call for heat exists and the Control will not go into lockout. The 2nd stage pressure switch fault diagnostic operation is the same as 50A51-405/-505 Controls. CNT2789 13 Thermal Protection Devices At any time during a call for heat, if the Control senses the high temperature limit (and/or aux.

Limit) or flame roll out switch(es) are open, the gas valve is de-energized, the induced draft motor is energized (low speed on 50A51 Controls), and the indoor blower is energized to run on heat speed. On models utilizing fusible link devices, the fusible link is a single use device and must be replaced if it has opened. However, if the temperature the fusible link senses is approaching the trip temperature but does not exceed it, the contacts may open and close intermittently. The Control will initiate another ignition sequence upon the closure of the intermittent fusible link. Flame Sensed With Gas Valve Off At any time the Control senses a flame current signal without a call for heat or when the gas valve is de-energized, the induced draft motor is energized (low speed on 50A51 Controls), and the indoor blower is energized to run on heat speed.1 The Control will go into system lockout and will not reset until this fault is corrected. The diagnostic LED will begin flashing 5 times to indicate the flame sensed with the gas valve de-energized. 1 See Integrated Furnace Control Label or Timing Chart.

The low voltage side of the transformer supplies 24 volts to the control through terminals “TH” o and “TR” i. Control terminal “R”; supplies 24 volts to the “R” terminal of the room thermostat. Once power is applied, the control flashes the LED “ON” for 1 second and performs a self check routine.

Following the normal system check, the control flashes the LED light once per second continuously (slow flash) while in stand-by. On a call for heat, 24 volts is applied from the thermostat terminal “W” to the “W” terminal; on the control. The control checks and confirms normally closed contacts at the temperature cut out “TCO” f, the auxillary limit (downflow and some upflow/horizontal models), the flame roll-out fuse link (two fuse links are used on downflow and upflow/horizontal models) f and j and normally open contacts of the safety pressure switch “PS” f. With all safety and control switches in their proper position, the control will energize the induced draft motor y and flash the LED light two times per second continuously (fast flash) during a call for heat. When the safety pressure switch “PS” f closes, the control begins the ignition sequence.

The hot surface ignitor y is energized for several seconds (see note) allowing the thermal element to heat up. The control then switches on 24 volts to the gas valve “MV” termi- 14 nals #1 a. The redundant and main solenoids are energized allowing gas flow and main burner ignition.

When flame current is detected by the control through its terminal “FP” k, the 45 second indoor blower motor delay on timing begins. Flame failure response time is set for 2 seconds. After flame has been established for ten seconds, the flame failure response time is reset for 0.7 seconds. If flame current is not sensed by the control k within the trial for ignition period (see note), the redundant and main gas valve solenoids a are de-energized. The control will begin a interpurge cycle and adds additional seconds to the hot surface ignitor warm-up timing (see note). The control energizes the gas valve a for the second attempt to establish main burner ignition.

If flame current is not sensed by the control on the 2nd retry within the trial for ignition period (see note), the control will repeat the previous cycle one additional time before locking out. At the end of the indoor blower delay on time, line voltage is applied at the controls terminal “HEAT” 5 energizing the indoor blower motor at heating fan speed, supplying warm air to the space. When the thermostat is satisfied, the gas valve’s redundant and main solenoids a are de-energized, extinguishing main burner flame. Once the control senses loss of flame current (0.7 sec.) k, the induced draft motor t is de-energized after a five second post purge cycle. The indoor blower motor delay off timing begins. At the completion of the fan delay off timing, the indoor blower motor 5 is de-energized and the cycle is complete.

Note: See Timing Chart for details or Integrated Furnace Control Label.
