Yup

Gas supply pressure was fine.
I should have mentioned that in previous post.

You're absolutley right, hands.
When the gas valve was energized, I had -1.3" w.c.---there wasn't enough gas being put out to raise that negative pressure up to -0.2". Tried adjusting gas valve's...

Thank You!!

Thanks Er14ic, I think the diffuser plate was clean, but I'll take a nitrogen bottle up with me next visit to be sure.


No I don't, if the manifold pressure goes from -2.5" w.c. to -1.3" w.c....

Hello everybody,
I got an issue with an older Trane Voyager pack that isn't lighting up in heat.
The model is YCD150B4LOBA
The ignitor was bad, so I got a new one, and installed it. On first...

A lot of times I use three different methods of leak detection to find a leak. The first is to look for oil stains, or get the general area with a "sniffer". I use an Inficon, and am happy with it....

On a couple of maintenance calls I've replaced a worn looking thermocouple, telling the customer "this is cheap insurance, it's sure to fail soon". I replace it and now the pilot won't stay lit. The...

Found a cool site that has a simulator of a VAV system. Pretty fancy!
I downloaded the simulator and tried it out. You can change parameters such as intake air temp and other things and watch how it...

Thanks for the info toolslinger!

Thanks for the site and advice maxster! I have the site in my favorites, and a binder in my truck.

Mall maps! I'll be scouting for 'em! Thanks!

Thanks for the site xcel!

Very good advice!
I have a defined line that I will not cross. I found it good to have that line defined before the situations pop up, that way there's no rationalizations, excuses made, or caving...

I'll definitley keep that in mind Jerry, it would only be as a last resort. Things weren't looking good there, which caused me to start looking elsewhere in the first place.

Well, I managed to talk to another tech for a while who works at this place too. Come to find out there is a couple of techs who have worked there for over a year. I also asked him if they deliver on...

I'm gettin' it, Timebuilder. It's been a learning experience.

I think who's getting milked the most is the employees. The more I read the Human Resources legalese in their employment manual, the more I see how things are rigged to legally deny the health and...

Thanks Hungrytech.
You're right about interviewing the company as well as being interviewed, next time I'm going to dig a little deeper.

Thanks, madhat and timebuilder.
Think I'll be gettin' the resume back out.
Just signed up to hvacagent.com.

Sorry that paragraph at the bottom of the post---wasn't supposed to be there. Please disregard. I looked for an edit button to get rid of it, guess there isn't one.

Hello all!
Sorry for the long post, I've tried to make it short as I could.

I've been a residential HVAC tech for 11 years, working for the same company since I left trade school.
I'm NATE...

Restricted/ collapsed return air duct?

I don't think I would suspect the reversing valve. If it leaked I think you would have lower head /high suction pressure.

Dirty filters inside the house? ...

You're right, I was thinking of a heat pump only thermostat. I was under that impression when martyinlincoln said to use emergency heat in the above post.
If the tstat can be configured to...

That would work, but I would be hesitant to do it in a customer's house.

Somebody in that household (relative, visitor) is going to put that heat pump stat into "Heat" mode. Sure 'nuff--that...
