Circuit Board Issue Root Cause

I rarely used the the furnace and have been bearing the cold due to its mediocre quality. The technician repaired the circuit board after very little use. It worked intermittently after that, leaving me in the cold 95 percent of the time - the personal ceramic heater has been my friend. I recently debugged the unit and found the circuit board is bad, as many people complained. I root caused it due to the cheap thru-hole technology and bad manufacturing process that the connector has insufficient solder on its pins. That it became cracked and loosened after plugging in or usage. The best way to install the circuit board is to plug in the connectors first, then affix the board to the stand-offs to avoid pushing hard on the connectors to plug in after the board has already been mounted - basically a reverse process. So, check the big 12 or 15 pins connector on its back at the solder joints when the circuit board fails. The furnace is now running, but a little rough, not sure what-else or just some minor adjustment. Cross my finger on the Goodman.

Do Not buy a Goodman Furnace

Do not buy a Goodman furnace! Its a money pit! I have spent over $1,300.00 repairing my Goodman furnace in the past 5 years. The main control board has been replaced twice & now needs another new board. The poor design over heard the board after a couple of years. They know it but will not replace the board. Not a good product. Maybe they should change their name to Badman.

Installed on 2007. Had replaced under warranty the gas valve, Two years later the lighting sensor and now the control board. Stay away from this maker. Cheap-made, unreliable product.

Faulty control board

Brand new unit installed yesterday and board failed in 3 hours. No heat again. Warranty company and Heating tech trying to get new one from Goodman but they want old unit back before they send new one out (leaving me without heat for another week plus)

Absolutely horrible furnace

We bought our home in Nov. 2009 and was told the furnace and central air were brand new. Well I can tell you that this system is horrible!!!! We have had to spend 300.00 to 500.00 every single year to get the furnace working. The mother board has burnt out 3 times. The Glow plug has gone out 4 times. The central air breaks down every year as well. Do not waste your money. We should have just had the whole thing replaced by now. So much for buying a home with a brand new system!

Very poor quality

I have had this furnace for 12 years and had to have the digital board replaced 5 times. Very costly and very irritating every 2 years.

I lived in 10 year old construction. Every two to three years the circuit board is fried. How is that possible? I one of many on my block . A claim was filed with Goodman corporate, which was a waste of time .They are standing by an original 5 year warranty. I'm sure history will repeat itself, so in two to three years it will have to be replaced again on me. I'm one of several people of which this has happened to. Next step: small claims court.

Installed in Nov 2005, first year control board fried,replaced lasted 3 years. Told was too hot inside cabinet. Double piped exhaust flue, you can put your hand on it when furnace is running. Also ran without the door on. Lasted another 3 years. Just installed the fifth control board Feb 2014. The last two boards showed no signs of a heat problem. You just have junk boards. Made in china I think !! Will never recommend any of your products, if anyone asks well you know junk.

Nothing but problems

This furnace is not even 7 years old. I have had nothing but problems. Within 2 weeks the control panel fried....of course not covered. I have had the heat filament replaced 3 times the heat exchange once the heat sensor twice. It never lights consistently. I have had no customer satisfaction.

Bad mother [board]

Sitting here today with no heat. We have just blown our 5th mother board. This is absolutely ridiculous! I do not know how this company can get away with this. Count me in on a lawsuit!

An expensivie, poor quality product

We had a Goodman gas forced air furnace installed on 03/07/2007, model # gds80703ax. The unit has only been used for 3 full heating seasons (2008, 2009, 2010). The unit has consistent breakdowns, usually in the early morning hours (2 - 3 A.M.). The circuit board has been replaced 3 times. The inducer motor was replaced in 2010 along with the limit switch, flame sensor, and gas value. We will never own another Goodman furnace or product ever. It is an expensive, poorly made, cheap quality product and Goodman is actively ripping off consumers.

Not so good!

Bought the Goodman gds8 in 2004. Had to have the mother board replaced in 2007. Now it's January 2011 and the furnace intermittently refuses to cycle and goes into lockout. Have had the service tec. here twice and can't find anything wrong, but we still get charged for a service call. Tonights suppose to be 10 degrees. Wish now we hadn't got a Goodman! It's very frustrating knowing somethings wrong and not being able to get it fixed!!

Had goodman gds8 furnace installed last year. Propane fired 70000btu. Extremely noisy, old unit was silent in comparison. Failed this fall at start of season and took two service calls to get operational.If I had the option and still might replace it regardless of cost.

Other GDS8 Reviews

A post on includes several opinions about the lack of quality among Goodmanís furnaces. Among other comments, an HVAC technician states that he would choose another brand over Goodman, as he has repaired many Goodman furnaces over the years. However, another reviewer counters that he likes the easy access made possible by the open design and the accessibility of service parts.

A Goodman owner writes to about a problem with his 80 percent AFUE gas furnace: the unit always cycles twice before the burner lights. Experts responding to the query can't seem to agree on what is causing problems with the firing cycle, suggesting a sticking gas valve, a bad capacitator or damaged wiring, among numerous other potential faults.

Several posters defend Goodman furnaces on One review mentions that Goodman offers the same equipment as other companies at lower prices. These contractors recommend checking out the installers in the area; a proper installation of a Goodman furnace is better than a poor installation of a more expensive brand, they advise.

Another post on mentions that Goodman sells equipment to anyone, not just licensed dealers. This results in many improper installations, and from this scenario Goodman gets a poor reputation. Several experts say the Goodman furnaces are similar to other brands; proper installation is the key.
