Rheem problem

[epschmidt]

Our service guy is stumped on a Rheem RGEO07EMAGS, serial #BU5D602M-M3192-1283. Pressure switch makes, gas valve opens, ignitor comes on, gas smell by exhaust pipe, no fire! Has anyone run into a similar issue. We suspect that the furnace is about 22 yrs. old.

Has your technician checked gas pressure?

You need a better tech- one that understands proper diagnostics & sequence of operation.

Twilly says go to Raheem.com and find contractor.

Make sure they send a dealer familiar with that POS. They were pretty tempermental. I think we finally got rid of all of them from our customer base!

I realize that furnace is a POS but was looking for some help trying to get it running for a customer that has had some tough times lately. Some of your replies have been neither helpful or without sarcasm. I guess when I entered this site I thought it would be for my benefit not your entertainment. My tech has 25 yrs. experience, yes the gas pressure is where it needs to be. Please do not reply if have nothing positive to say. Precision hvac you strike me as being one of those guys that thinks everyone is an idiot but you.

We cant get into any real specifics since you dont have pro status. You didnt provide any details, even as basic as gas pressure entering and leaving the gv so that leads many to believe you are a homeowner trying to fix his/her own furnace.

I am new to this site and probably signed in to the wrong area. Yes we are a HVAC licensed company. From what I have found out so far about this unit they are a problem child. I thought someone on this thread would be able to give me a direction to look.Gas pressure (natural) on the burner side was 3.4 in.. Ignitor comes on but the flame will not make.

[ar_hvac_man]

Sounds like there may be something blocking the flow and the gas isnt reaching the ignitor.

Twilly doesn't doesn't think we are being entertained. The site rules are clear and DIY advice isn't allowed. Your post is confusing, are you an HVAC contractor? Twilly says you say your tech and your trying to help your customer.

If your tech of 25 years can't figure it out, why are you angry that Precision told you to find a more qualified tech, Twilly thinks thats good advice.

ar hvac man, we did clean the burner, orifices and screen. I've been told that on that model the ignitor has to be no more than 1/8 in. from burner gas flow. We'll check that.
Thanks
