Review: easy fix for the 3 blink error (pressure switch stuck open) - To preface, a week ago I had very little knowledge of how a furnace really worked. So it finally got cold this fall and I turned on the furnace for the first time a few days ago. Crap, no heat. After checking the furnace, I got a couple different errors. First, I was getting 3 blinks, pressure switch open error. The inducer motor would come on but the igniter would not get hot and obviously no flame. After watching a few youtube videos on how to diagnose common furnace issues I was able to get a good grasp on what to test. Testing the pressure switch was easy. All you need to do is put your voltmeter in continuity mode and place the leads on it. There should be no continuity when the inducer motor is off. Once the inducer motor comes on and causes the draft then the change in pressure will close the pressure switch and cause voltmeter to beep if it's in working order. My inducer motor was starting and closing the pressure switch reliably yet I was getting the pressure switch open error. Hence I knew most likely the board was bad. After more testing, a 2nd error I was getting was a continuous single flashing light. This time, the inducer motor would come on and the hot surface igniter would glow bright but no click of gas valve and again no flame. This rules out the igniter as a problem. It also effectively ruled out a pressure switch being the issue since the igniter would not come on without the pressure switch closing. Could it be a gas valve issue? Possibly, but from I've read they rarely fail. The way to help diagnose the gas valve is to test for voltage to the gas valve. You should get 24V to the gas valve for it to open. If the hot surface igniter comes on and you get voltage to the valve but no flame, then the valve is bad. If you don't get voltage, the board is likely bad. I had 0V to my gas valve indicating a board problem as I suspected. I ordered this board and received it two days later just as a cold front was arriving, replacing a 50A55-289 board which is no longer sold. The board layout was the exact same and it was an easy 15 minute swap. Firing up the furnace for first time was nerve wracking but after 20 seconds or so, everything fired up perfectly. I had just saved myself about $500 for a few hours of research/diagnostics/labor and a lifetime of knowledge. I'll likely pick another one for backup since they apparently fail often. Review: Perfect fit in a Goodman furnace in place of 50T55-289 - Our furnace suddenly stopped working during an unusually frigid week here in New Jersey. It kept trying to start up but the burners just wouldn't light up. I tested the usual suspects; the pressure switch, flame sensor, roll-out switches, HSI, but they all seemed to be within spec. All evidence pointed to the gas valve, since it was receiving the right voltage input, but it didn't seem to want to switch the gas open. So I ordered a replacement gas valve and resigned myself to calling one of the local contractors to switch it out once I picked it up, since I'm neither comfortable working with gas piping nor have the equipment to calibrate gas valves. Meanwhile, while waiting for the gas valve to be ready for pick-up, on a whim, I started doing further research on the furnace control board. It turned out that several people with Goodman furnaces had similarly switched out their gas valves only to realize that it was a control board failure. The control board on my furnace, part number 50T55-289-03, is no longer made or sold, but the 50A55-743 seemed to be the most promising replacement. At $50 (including next day), it was a relatively inexpensive bet. So I ordered it here, and it took just 15 minutes to switch the old one out and put this one in. I noticed two extra pins on this board that are optional and can be ignored, but it's otherwise identical to the board it replaced. Even the mounting standoffs line up. I turned on the furnace, and it went through the sequence, and then lit right up! I've come to learn that these Goodman furnaces have control board failures every 3-5 years. I expect it's because they don't have sufficient thermal/mechanical shielding. But at least they're fairly inexpensive and easy to replace. I'm ordering another one to keep on hand in case this happens again, but I hope that's another 5 years away. ## Features - Furnace board - Goodman furnace - Control board - Model number: 50A55-743 ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 926 Reviews | ## Images ![White-Rodgers 50A55-743 Control Board - Image 1](https://m.media-amazon.com/images/I/71kjAo1hnAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy fix for the 3 blink error (pressure switch stuck open) *by F***G on October 29, 2019* To preface, a week ago I had very little knowledge of how a furnace really worked.

I purchased and installed the board successfully. It works great! I am not an HVAC professional. The trickiest thing about the install was mapping and placing all of the old wires to the appropriate plugs on the new board. The new board was slightly different than the original. It had more plug slots. Upon examination, the new board offers more features, hence more plugs and a pin switch that wasn't on the old board. Thankfully the instructions and motherboard were well marked. I simply was carefull when moving the wires to ensure they were mated to the correct plug on the new board. Took 30 minutes - but I never did this before. On day 3 of use and it it working perfectly....Beat the almost 1,000 the pros were going to charge me (but you are paying for their knownledge, skill and the convenience). --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/13055065-white-rodgers-50a55-743-control-board](https://www.desertcart.no/products/13055065-white-rodgers-50a55-743-control-board) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
