Question on Goodman furnace, which decided that it would not work for the new year.
T-stat clicks on, inducer motor starts, after a few seconds I hear a click which is usually followed by the glow from the igniter, but that does not happen. After a few more seconds, everything shuts down and I get a faint smell of gas.
Is this behavior is consistent with (a) igniter or (b) pressure switch
That looks like the igniter from my old Luxaire/York furnace. (they are more fragile than eggs.)
You have an igniter problem. It could be a defective igniter or it could be the control board.
You need to use a meter to check for 120vac on the igniter when it should be heating.
Much appreciated. I thought it was the igniter because I smelled gas.
This Goodman is about 20 years old and original to the townhouse.
Since you guys do this for a living…..
If this were your home and you were replacing, the system because of age, what would you replace with and what is a good ballpark number? I’m in NJ.
Pretty sure the furnace is something like 45k BTU and the AC compressor is 2.5 tons. The townhouse is 2 floors and 1900 sqft. Both heat and AC work ok in normal weather and struggle a little in extremes, but I understand the builder designed for certain limits. Can’t really complain about that.
Hard to say without knowing more about the duct work. If you are running a great external static pressure (.5 or .6" w.c.) then a 2 stage outdoor unit with an ecm indoor blower 2 stage furnace is an option to consider.
If you are running high external static pressure (~.9"w.c. or above) then keep a similar setup.
We get strong winds and gusts that can come from 3 directions - the left, straight on, and the right.
1. Could this cold air blow back into the furnace between heating cycles, thermally shock the heat exchanger, and shorten it's life over time?
2. I've considered building a 3-sided box, open at the top and bottom to surround the vent pipes, preventing the wind from blowing directly on the vent elbows.
3. The furnace installation manual mentions wind gusts but offers no solutions to the problem.
I would appreciate knowing how to solve this problem.
Thanks very much, and Happy New Year!

I don't know what else to do!
My oil burner was working well, but the fuel shut-off valve was jammed open & it was 60+ yrs old, so I decided to replace it! Wow! Can't even figure how the burner fired when I saw all the "crud" in there! Anyway, long story, short, figured I would change the filter, nozzle & pump screen & what a mess! Changed everything out, set electrodes & put everything back together! I bled & primed & fired up the burner, but now every time the burner fires up, it starts right up & runs great for a few seconds, but then starts rumbling & "booming"! After a short time it smooths out again! What's the problem? I thought maybe air, but thoroughly bled everything! I also blew the oil supply line out & reprimed up through the filter! Any ideas?
