5amp fuse blowing

[Bmurph1409]

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

just keep changing parts youll get it eventually and call someone who knows what theyre doing. It would be cheaper to stop now a call a certified tech to fix it. When you try to go cheap you usually end up paying twice, or in your case 5 times and counting.

I hope you are messing with us!

Just take the fuse out then! They are such a pain anyway.

Could be the condensing unit. Why have you replaced so many parts without isolating the actual problem?

Dang that's an expensive fuse, just get one of those varitey packs of automotive fuses and step up one size at a time till it holds.

No I'm not. And I am universal epa certified. And the gas valve was first bad which is why I changed it and I only changed blower because home owner asked. I have asked many other techs I know and no one think of what it could be.

[Bmurph1409]

One I have replaced the fuse two I did the gas valve because that tested bad first day I was there three only did blower because home owner asked because it was extremely load. And I did the thermostat because the wires were spliced and some exposed. So now why do you think the fuses could still be blowing

[BigBacardi]

the solution is to just replace the parts that u havent done yet...... eventually u will fix problem

[jtrammel]

what does being epa certified have to do with the price of beans in africa? Theres only so many things a LV short could be a good tech would find the problem before unneccassarily changing parts. Why would a homeowner want their blower changed if it wasnt bad?

[Bmurph1409]

Wow what great help not really. How about someone who actually knows about this because even ducane tech couldn't figure it out.

3 amp fuse in a 5 amp slot?

[Bsmith816]

If I was you I would have done the smart thing... Called a service technician

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.

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?
