It is a problem on your low voltage side. I had the same issue and found that my wire going to my outside condeser had been snagged on a wire hanger in my basement and was shorting out the system. I went a head and replaced the entire wire from my outside unit to my indoor and haven't had an issue since. So my advice is go to HD or Lowes and purchase some 14 gauge wire and replace the low voltage wire. If that doesn't work, then replace the thermistat wire, and thermistat. Great time to upgrate to a energy efficient thermastat.

This fuse is used on the low voltage side of the furnace. All 24 volt controls operate thru it. You may have a short in your thermostst, thermostat wire or even a bad transformer. After replacing the fuse, inspect the wiring in the cabinet as well as the wire heading toward the thermostat for damage. If you find none, check the thermostat for loose wires or contacts. If all else fails, jump out R and W with a small jumper temporarly at the furnace and see if the unit runs. You will have to tape the door switch closed to run it with the panel off. Remember, this will keep the furnace running 100% of the time until you disconnect the jumpers. Not a solution, just a test! If it runs flawless, you have a bad thermostat or wire. Diagnosing a transformer is for a technician.

Heater fuse blows when ac is turned on

poor Wire connection on the breaker? Is the wire screwed down tight? SHUT THE MAIN OFF FOR SAFETY, then pull the breaker off the buss bar and inspect the bussbar and bottom of breaker for any burn.

the 271n is a Trane round igniter and the 271nm is a Goodman flat igniter other than the shape and size there is no difference either will work fine allot of time if you touch the igniter surface with your fingers the oil of your skin will make them burn out faster (like a halogen light bulb) I would keep one around in case of emergencies but it's not something you should have to change annually they do break and burn out but if it glows and after you replace it and the furnace works fine there probably isn't another problem. You should be fine.

Hope this helps dont forget to rate me.............

I have a Goodman high-eff furnace, 115 BTU/hr. The fan runs constantly but it has stopped blowing warm air. I'm getting 6 flashing lights as error code. What's this mean?

Remove the lower panel and look for a wiring diagram pasted to it. On that diagram there will be an error code diagnostic chart. Depending upon which model you have it could be an open overheat switch caused by a dirty filter or a bad fuse.

Goodman unit blows 45 amp fuses only in heat mode, worked fine all summer on a/c. It works well for some time then blows them again.

Check the breakers on the unit How many KW--electric heat? Check to see if you have the right wires wired up to the correct breaker cause some units have 40---and ---60 ---amps breakers and your thickest wire could be wired to the 40-amp breakers,, (some 5 KW pullls 19-23 amps respectably some breakers have 7.5 KW heat stips and pulls more and if the wire size can,t cary the amps, then all you have to do is reduce a heat strip.

3amp fuse keeps burning out

Hi,

when a fuse blows, its telling you that theres a fault. this could be a loose or broken wire.
or alternatively, the fuse rating is too low. you could check the wires are tight. and also possibly try fitting a 5 amp fuse. check first that the fuse is rated correctly for the appliance. usually 3-5 or 13 Amps.

Goodman Furnace/AC unit not working 3a fuse blows even after replacement. once thermostat is turned on and clicks to start ac unit the fuse blows

3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.

The heat works perfect but when I call for air it does not do anything

Make sure that the thermostat is on Cool and that the outdoor electrical disconnect is on. If you still do not get cooling, there may be a fuse that needs replacing or other issues.

Transformers and fuses keep blowing

If you are where it's warm and you are using air conditioning, have the technician check the coil in the relay in the outdoor unit. I replaced 2 transformers before I figured out the coil was shorted out and drawing too much current.
