#219606 Converting a valve DSK-65-LP

Posted by Dan Webster on 05 January 2012 - 09:06 PM

You cannot convert that valve based on what I see that thing is factory set and not servicable in the field...I may be wrong...been wrong before. I have a truck full of essex valves by the way.


#219333 Converting a valve DSK-65-LP

Posted by Dan Webster on 04 January 2012 - 12:33 AM

That big flat blade screw has a push pin under it. Remove the LP pin out of your old one and put it in that 3.5 valve if you have LP gas. If you have then nat gas then use it like it is.


#219141 Help with Flame Rectification specs on Coleman/Evcon DLAS056BDC furnace

Posted by Dan Webster on 02 January 2012 - 12:45 PM

My friend a tv repairman that works at the wings of life as a volunteer told me he removed the cover on these modules and has had quite a bit of sucess in soldering a loose connection on the pilot flame sensor ground terminal. The solder connection comes loose. Remove that cover on this puppy and look for a loose solder connection:

#218454 fan does not always work in heat mode

Posted by Dan Webster on 25 December 2011 - 02:43 PM

They use that thing to brang the heat on in stages to prevent tripping the breaker. You want the fan to come on after the elements come on. Not very familiar with these new fangled furnaces with electronics. A simple sequencer could work that furnace without them electronics. I know guys that just yank all that out and a mount a sequencer.

That black component in photo 165 is the fan relay. Single stack sequencer. Starts the fan on a delay so that the vents will be warm when the fan comes on.

Continuous flashing on the LED might mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram


#217655 REMOVING THE AIR BELL COUPLING FROM THE AGITATOR SHAFT OF COUPLING - GE WBXR2...

Posted by Dan Webster on 16 December 2011 - 11:23 AM

Most of the time the drive bell is wallowed out and slips right off. The hardest part is getting the bolt out. The bell comes with a new bolt. You must have a worse problem that a drive block. I bet the previous owner put some gorilla glue on the drive block because it was slipping. LOL


#217640 goodman gmpno80 goodman furnace... i blink... no gas flow

Posted by Dan Webster on 16 December 2011 - 09:54 AM

Good info Reg. I have these in my notes also:


A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.


#217585 Ruud ugph-07eauer gas furnace

Posted by Dan Webster on 15 December 2011 - 07:30 PM

Every since I been online I ain't been able to find out anything about any HVAC pages. As you may know their are a bunch of appliance sites out there but not too many HVAC sites.That is why I suggested the Samurai start an HVAC think tank on his marvelous site. He graciously accepted my suggestion.


#217481 goodman gmpno80 goodman furnace... i blink... no gas flow

Posted by Dan Webster on 14 December 2011 - 10:24 PM

What I would do is remove the wires from the gas valve and fire that puppy off. Check if any voltage is gettin to the valve. The board won't be sending any voltage due to multiple factors. Bad board (fuse) or Bad limit(s) being the first thing I would check.
Sequence of events in the life of a draft induced high efficiency furnace:

#216718 Goodman furnace gmt070-3 Blower works, gas comes on, no spark.

Posted by Dan Webster on 07 December 2011 - 02:12 PM

Unplug the ignitor quick connection and see if the ignitor has continuity. If it does then see if power is going to the ignitor. Hunt down all rollout/limit switches and makes sure they all are not tripped. If you find a tripped limit look for reasons why such as a partially blocked smoke stack, rusted burners etc. If all the switches are fine then the control board may need to be replaced.


#216717 Blower Motor not Reliable in HEATING mode - ArcoAire GUG070A012N

Posted by Dan Webster on 07 December 2011 - 02:00 PM

Well on older models you have a fan/limit that kicks the motor on. A probe is mounted inside the heater chamber and as the temp rises above 110f the fan kicks on. If the fan don't kick on then the bimetal continues over to the limit which kills the heat. Hence it is a fan limit and it looks like this.
On newer models the fan comes on after a timing sequence build into the main board. if that is the case ya probably have a bad or faulty board.
Note: it is impossible to look up HVAC equipment online. Photos of your stuff would be easier to diagnose.
