SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: Thermal fuse keeps blowing

Mr. Larry (guru?)
The thermal fuse is just that It doesn't protect the circuit from over current although it certainly can open in that case. It is there to protect the board from overheating , thus the term thermal. The dishwasher could be allowing the water to heat too hot or the water heater in the home is turned up too much. The heater could also be shorted to case thus allowing it to be on even though the control is not calling for it especially if the polarity is incorrect to the dishwasher or the relay on the board could be welded closed so that the heater can't turn off even though the thermostat is satisfied. The best thing is to get a person who can check these things. You don't necessarily need to change the board with a fuse. I have changed many fuses with no other problems and verified that the machine was still working years later. sometimes the fuse just blows!

Sounds like the Start capacitor might be shot.  I think  you need a professional to service it.

SOURCE: york central ac keeps blowing 3amp fuse on the

sounds like you have short in the low voltge side of the electrical circuit. I would check the thermostat wires outside at the condenser. look for any bare or exposed wires from where the wire comes from the house to the condenser. the thermostat wire will be a brown wire that is run on the outside which sends a signal to the contactor to make the condenser work. common cause his rodents or happens when weed whacking around condenser. Hope this get you started.

SOURCE: starter relay fuse keeps blowing

30 amps is heavy, so bypass nothing. Look for a short in a heavy circuit like the the headligh, starter (questionable because of delay) same with starter relay. You have a wire shorting out on the frame somewhere. It's that cut and dry.. Go to the auto parts store and buy an automatic circuit breaker that matches the fuse type your bike uses. but instead of a 30 amp, get a 20 or 25 amp. As long as theres a short it will trip and reset by itself saving you the hassle of changing fuse every few minutes.. While the breaker cycles on and off you can search for the short. When you find it, the breaker will stop cycling and stop in the on or reset. Good Luck

Have a hobart lx3011 and just quit working. where and how many fuses in it?


Not sure if you have an LXIC or an LX30.
Both have a pull out drawer at the top. Both have the main connection of power on the contactor in the front left corner. Both have control circuit fuses between the contactor and relay board.
Use caution with a digital meter to test.

Lx30h hobart dw. booster will not turn on. element good,hi-limit is good, changed temp probe, still no power to contactor


The booster heat control circuit is controlled by the relay board. Visually check for loose or burnt relay contacts...
You will see the booster LED light when it calls for heat. Some newer machines have a second high limit on the right hand side of the booster tank.
It may be your control board is configured for low temp with no booster. When you power up, the display should say LX30H. If not
Pull open the upper drawer, place a magnet over the door interlock switch.

CAUTION, 220 volt power is present. be carefull what you touch.

on control board, short J5-1 and J5-2, then power up. You are in factory setup. press select on the control board to see each option on the front panel., press up arrow on control board to step up through options for each step. when done, press the off button on front panel. remove short and start up normally. With the magnet in place, AND THE DOOR CLOSED, run the machine and observe the relay board status lights.
If you want to adjust the temp set points, with the machine off, press and hold the hidden key behind the front panel logo, and press select on the control board.. Or on power up, hold the wask key..Same to adjust options as above. Press off to exit.

Hobart am 14 constant power on rps 1+2, rinse conection has power even when machine is in wash cycle


DPS1 and 2 are fed from L1 and L2 directly.
RPS1 and 2 get their signal from a relay, triggered during fill or rinse. Check inside the control box for the machine schematic and component location. Check that the relay only powers during fill and rinse. Check for welded relay contacts.
Note. Soap and rinse dispenses are often spliced into AM14's in unusual ways, and with unprotected pump circuits. (no fuses) These can be too much current draw for the contact rating of the relay.

Commercial Hobart dishwasher


I can't imagine a bad relay board would blow a fuse. The relay board would need to make a bad connection to ground to blow a fuse -- I don't see it.

If you could supply me with the ML#, I'll take a look at the wiring diagram and give you an educated answer.

Not that I recall clearly which fuse is for the drain solenoid, but the two sound related. If a drain valve is obstructed by debris, it will heat up the coil and short it out. I don't know the spec'd ohms, but I would suspect at least 50. I'd check it.
