Amp fuse 30a keep blowing

You have possibly melted a couple of wires together along the radio circuit. Also the radio unit itself has 1 or more protection fuses actually inside the unit that have blown, usually at back of unit in little bay near the wire clusters.
Check your relays too, a blow out through jump starting can do all sorts of little burn-outs.

I have a Rheem Furnace Model # RGPH-07EAMGR Serial # FD5D307F16000271. The unit keeps blowing the 3 amp fuse on the ciruit board. I verified the amp draw from the blower motor and it is well below the...

Hi, this fuse is for your 24volt controls, which means anything that runs on or is controlled by 24 volts. Check the thermostat wires at the board where they come in, as I have seen them skin the insulation and ground out blowing this fuse. The contactor coil on the outdoor unit is 24 volts and may be shorted. Its a matter of looking at all of the low voltage wires to the indoor and out door unit. If you have a dog, I have seen where they chew the wires causing a short, or from the sun causing the insulation to come off and short.Something is for sure causing a dead short on the control side, It would not be the stat unless you have been into the wiring behind it and maybe the R, red is touching. (9 times out of 10, a low voltage wire is touching metal or another wire, common. If all of the wires look good, you will need to do the process of elimination. Go to the outdoor unit, and the wires coming outside from indoors, if its a gas furnace, you will have 2 wires. Take them loose, and this will take it out of the circuit. Now try another fuse. If it holds, your problem will be in the outdoor unit. It would have to be the contactor coil. It has 2 small wires, one on each side. Pull them off, tape them so they dont touch and wire the 2 wires coming out back up. When you restore power to the outdoor unit, if it holds you will know its the contactor, it has points on it and this is what closes to start the fan and compressor, just 24 volt coil. This is not a high voltage problem, only a low voltage, so checking the amp draw on motors are wasting your time. After you eliminate the outdoor unit, take each wire off of the terminal block at the indoor unit. Write down how they go back!! This eliminates the stat wire and thermostat. If the fuse holds, you problem is in the stat wire touching in the wall, or at the stat. Most contractors will have an extra wire that can be used. You will need to ohm out the wires to see which is touching. Last thing to do, is kill all power, and remove the 4 screws on the board. It will have stand off's on it to keep the back from touching metal. Look at the back to see if it is burned any where on the raceways. If so, you have a shorted board. Please follow all of my steps and you will find this short. It is really very easy, now that you know its the low voltage side blowing the 5 amp plug in fuse. Process of eliminated the parts like the outdoor unit, thermostat by taking off the wires at the indoor unit and so on. You will find it. Please let me know and rate me on my help to you.

Thermostat keeps blowing fuses

There is a short in one of the thermostat wires. The fuse is triggered on the low voltage side of the unit. Replace the wires.

TV won't turn on

take the back off the tv and inspect the glass fuse off the ac power cord, it will probably be black and open, this is a common problem, it blows because the degaussing circuit works too slow, the original fuse is an 6.3 amp fuse, you need to replace it with a 6.3 amp slow blow or a 7 or 8 amp fuse to keep it from blowing, if you put an original 6.3 amp fast blow fuse in it, it will work for a while, but will blow again someday.

Goodman GMP75... keeps blowing fuses only in A/C mode. Only when I connect yellow wire from thermostat to line going to condenser contactor (24V side).

Are you talking about the small 3 or 5 amp fuse in the furnace? If you are then the control voltage circuit to the condenser is shorted, Maybe dogs or rodents chewing it or the insulation is cut by a sharp piece of metal. Sometimes the contactor will go bad and cause the small fuse in furnace to blow. Look for the simple things first, like control wires shorted. Make sure the yellow wire from the thermostat goes to the outside unit and not to the common.

125 v 4 amp fuse keeps blowing

if you plugged a 125 volt tv in to a 220 volt outlet you more than likely fried alof of the componets in the tv. Putting a bigger fuse in there is only going to increase the risk of it catching on fire so i would not recomend that. you might replace the power supply and cross your fingers and hope that nothing else cooked when the 220 volts hit it
