Hi,

Most likely a sequencer problem.


Sequencer # 901076 can be seen and ordered from here by paging down to it :

Hi,

Inspect the burner tube and burner orifice/spud for clogs/blockages (spider-web-bugs).

IF all clear, will need an hvac tech who knows his trade, the last one does/did not qualify.



Thanks,
Robert

Did you check the gas valve for 24vac ? Check the burner tube and burner orifice for clogs (spider-web-bugs).



Thanks,

Hi, Go here for steps to troubleshoot your Blend Air System: http://www.mobilehomerepair.com/hvac/ArticleBlendAir.html You can disconnect it for now and work toward finding the problem and repairing when it is warmer. It is a separate system from your furnace and is not needed in order to operate th...

Hi, I deleted the other extremely long post because I do not have time unfortunately to read all that and do not need the sequences of your furnace operation spelled out for me. It also may have some info that is not allowed on here for the viewing public. Here is a link for my troubleshooting fee i...

Hi,

It may work, but the reason it was not getting voltage could be due to a safety issue interrupting the power to it for safety.


IF that was/is the case, doing what you did bypassed that and could create a dangerous
situation.

Hi, What you described could be the sequencers or the limit switches. Only way to know would be to test them when it is happening. Anytime your furnace is not functioning properly, there is a risk of an electrical mishap causing a fire IF you continue to operate the furnace. I would only replace wha...

What is the furnace model number ? The gas valve not working may be to a safety issue, jumping it could prove dangerous and is not advised.



Thanks,

Hi Terri, Ok, you've been reading some in the forums it appears. Meter set to read above 240VAC, one meter lead on far right and other lead on far left coil terminals on white ceramic insulators. WITH a call for heat after 30-45 secs., you should read 240VAC across them. IF you do not, send me an em...

Hi Barry,


Keep me posted if you need anything else.



Thanks,

Hi Rob, That was the next thing I was going to ask IF the flame sensor cleaning did not help. ALL Coleman furnaces that fell under the recall program needed to be inspected and repaired if there was a problem. You could have issues with your heat exchanger. IF they do not find anything wrong or cann...

Hi Terri,

You will need to find someone with experience in using it as this is high voltage and too dangerous for a first time DIY attempt at it.


Thanks,
Robert

Hi Rob,

Pull the remote flame sensor and clean the rod with steel wool. Do not touch it with your hands and be careful not to damage the ceramic shroud.



Thanks,
Robert

Hi Jim, For the heating elements to become energized, one of two things must occur. Either there is power getting through on the sequencer side due to a short or stuck sequencer contact. Or, part of the element coil has fallen down and is touching the frame or wall of furnace creating a pathway back...

Hi Terri,

Do you have a volt meter or can you get one and do some tests or have a neighbor/friend that can do some tests ?


Thanks,
Robert
