    OOOPS!! that was supposed to be a "clarification request."

    Obviosly that question will not solve your problem. Would you be so kind as to wait until we have looked further into the problem in order to have a chance to solve it before rating the "solution"?

    OK that means that there is a specific component that is pulling to high of an amp draw.

    Most likely a motor.

    After the unit has been running for about 15 min, check the amp draw on the blower motor. Let me know what that motor is pulling.

    Also let me know what amp fuse keeps blowing.

    Is your system a heat pump, gas furnace or electric strip heat?

    With a good amp meter, a little patience and some trouble shooting we can get this problem solved.

    (and maybe result in a better rating eh?)

    Ok, in order to diagnose the problem, we have to know the amp drw on the blower motor, and each heat strip.

    We also have to know the total amp draw on the furnace when all the strips are going.

    You probably have a fan motor thats going bad, or possibly a heat strip problem. We can help verify or eliminate each as a problem once you check the amp draws as I suggested.

    Let me know what those amp readings are.

Will it hurt to replace the 20 amp fuse in my cigarette liter to a 25 amp it keeps blowing fuses

I am wondering if the fuse blows instantly or whether it lasts a while?

Fuse ratings for cars are usually mean or average values so a 20 amp fuse needs roughly 40 amps to cause it to instantly fail. I have not heard of a cigarette lighter needing that much current so I guess there is a fault that should be located and cured before you have a fire.
Maybe it is the element that is faulty...

I think fitting a 25 amp fuse would be slightly foolish...

My 2008 suzuki grand vitara keeps blowing the fuses for the ACC outlets. both are 15AMP, but even with nothing plugged in, nothing down in the outlets and even with larger AMP fuses, they keep blowin

If you use too large a fuse, the wiring can catch on fire, and the whole car could burn up. You'll need an auto electrician to trace that problem. You can remove any bulb and unplug any device that is on the Acc(essories?) circuit; then see if a fuse will stay; start replacing items till you blow the fuse. It seems like a dead short which can surely melt wires if you keep taking chances. good luck.

fuses blow because of excessive current flow from a dead short to earth. You haven't stated which fuse blows and what the items are covered by that fuse. so check the power wire from that fuse and trace it until you find a burnt area or a place where the power wire is touching the body before it gets to something it is running

Maybe try going up 5 on the fuse, its a little risky but it should work. If it doesn't work you may want to check your wires for a short that may be causing the fuse to blow

1997 GC Jeep, 4.0 L . Keeps blowing fuel pump fuses. Told that 20 amp was recommended.

You should always replace fuses with the same rated fuse as the one removed. Most likely if it keeps blowing the same fuse something in that circuit is directly shorted out.What fuse is it that keeps popping?

Chevy silverado keeps blowing fuses

Your 20 amp fuse will not blow if glowplug wire shorts. each plug draws 15 amps which is 120 amps total.I think there are in line fuses for them. Try to wring out where each output from the fuse goes, disconnect all and reconnect one at a time till it blows.That should point to your problem process of illumination! Good Luck!!

Toyota Camry 1994 Main Fuse keeps blowing

-if your fuses are blowing
-the problem is in the wiring
-because if too much amperage flows through the fuse will blow
-there's probably a short to ground somewhere or high resistance after the fuses causing it to draw more amps

Keep blowing fuses

hi, make sure you are using a time delay fuse and not a regular fuse. this may be the reason why the fuse keeps blowing out on your dryer.
