      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

Goodman Furnace lesson learned - trust by verify!

Recommended Posts

I was reading through the excellent troubleshooting thread and reminded of an issue I was having with my Goodman high efficiency furnace. It was a couple years old and it kept cutting out. I would run for a while, then stop for a while, then run for a while... It was throwing a gas valve code and then it started not running more than it was running so I called for service (under warranty, thankfully). The tech checked the system out and one of the drain tubes for the heat exchanger was full of water. He cleaned out the tubes, put it together and it ran fine. Was near the end of the winter, didn't think much about it.

Next winter, I had the same issue - it worked for quite a while, then started locking out. When checked, water in the tubes. It only happened a couple of times and clearing the tubes solved the problem so I didn't think much more of it.

When it started for the third winter in a row, I started to suspect something might be up :teehee: (OK, so sometimes I'm a slow learner). Luckily the installers left behind all the documentation including the installation instructions. So I started to read them. Lo and behold, there are two drain ports - one for horizontal installations, one for vertical. It most come configured for horizontal from the factory. So I swapped ports and haven't had a single issue since (for two winters now). D'oh!

And yes, I read through and double checked everything else in the install guide just in case! Don't always take the error code at face value and don't always assume the last guy did what he was supposed to do. Probably obvious to the pro's in here, but it's something for us enthusiasts to constantly remind ourselves :pint1:

No matter how careful you are or how good you think you are S happens.

I did a install last December and failed to move the drain hose from upper to lower and had a similar problem.

Fortunately,I ran the system overnight in a remodel construction to check it out.

Found the issue the next morning and fixed it.

Like I said....S Happens.

Thanks for pointing this out.

True - it was an install for new construction, so it was probably just overlooked. I'm sure the builder compensated the HVAC whatever the minimal amount was. I do have to hand it to the sheet metal guys - the ductwork on my ground floor/basement is very neat and tidy, and it was installed cleanly - even the joints were taped with foil tape! They used more flex duct that I would care for in the attic, but so far no issues.

It was still annoying it cost me a service call before I got curious and figured out the root cause :thumbsup:
