were not allowed to give DIY advise to non pro members. If you are a tech, get your post count up and apply for pro membership. You will get all the help you need then, but until then you will not get any useable advice. What is a "Ducane Tech" a gas furnace is a gas furnace to a tech, they all work pretty much the same.
how many places do you have to post the same question?
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."
from an excerpt by Paul Jacob in Sun City, AZ
This thread is an eye opener for me. Working in a factory run testing units, they wont let me just change parts out if fuses are blowing. They ***** at me if I blow a second fuse without finding the problem, let alone just changing boards, blowers and thermostats. Is this how stuff is actually done in the field?
Wow what great help not really. How about someone who actually knows about this because even ducane tech couldn't figure it out.
and none of us can figure it out either. We can only lead you in the right direction. Check your low voltage conductors and loads individualy. Please remember, You are not entitled to my knowledge nor that of anyone elses on this board. How about being a littless rude.

It was working when I left...
Liberalism-Ideas so good they mandate them
I've been working on a ducane gas furnace and have replace almost every part but the 5 amp fuse keeps blowing every 6 hrs or so. I even changed the thermostat wire the t-stat itself, the control board, the gas valve and even, the blower and it still blows could it be the condensing unit
You have a time line here what sequence of events takes place every 6 hours? Remember the five basics of trouble shooting
3Attempt to operate the equipment
Important note : If there is a remote chance of possible damage to personnel or equipment SKIP THIS STEP.
4 Voltage checks
check supply voltage first , then control voltage
5 Use the documentation (i.e. ladder drawing) and the appopriate test equipment to logically troubleshoot the circuit and isolate the problem.
If you have replaced all the parts its possible something was rewired incorrectly.
Above all remember be safe if you do not have a good feel for you level of competency. Do get the correct help and learn from the pro.
