SOURCE: I have 2 Laars Mighty

Hi Don and welcome to FixYa, I am Kelly.
I first have to ask a question: Is there any sign of water being introduced into the firebox? Fused links open due to high current flow. High current flow is caused by several things:
1. Chassis grounds
2. Failed components
3. Corrosion on terminals
4. Hot terminals of wiring connections (even main power) on terminal blocks or components.
5. Clogged flue or litle air flow out the flue so the unit is getting very hot inside the chassis.


Since you have 2 units... I would be doing some serious resistance comparisons between the 2 units.

Take a look at Figure 16 on page 22 of this manual: (All 24 VAC related)
http://www.laars.com/LinkClick.aspx?fileticket=xpEyS3kHr3U%3d&tabid=1607&mid=4009
The fused link is the fuse for the fan switch, flow switch, Ignition BD, Gas valves and relay via the pump switch to K3. You need to compare the readings between the 2 units in this circuit. Somewhere you have a very LOW resistance that is cooking your fuse link. I think your going to find the problem is either with the ignition BD or the gas valves. If you suspect the ignition board as the probable cause move the boad between units. If the fuse link fails on the other you you know the board was bad. If the fuse link fails on the unit with the original symptom suspect a problem with the gas valves or relay K3.

Thanks for choosing FixYa,
Kelly

Ford Focus 2006 1.8 tdci fusebox making buzzing sound central locking won't work and car won't start


Sounds like a serious wiring problem. I would advise you to have this looked at or fix your self before using the vehicle. I had a car catch fire because of a similar problem many years ago. Could be a simple fix if you can locate the wires causing the problem. But finding one at the fuse box will prob be very difficult.

Turn hot water on and it takes a while to heat up and when it does it will sometimes get cold and then come back hot..Back and forth..Started about 2 weeks ago....


Sounds like an issue with your gas valve needing cleaning or your thermal couple. Prob more the gas side. You need to turn your hot water on and watch your heater fire. See if it stays lit or if it fades in and out. Could aslo be the gas valve. The prob is pretty vague. Also look at the age if its more then tens years or near old. You might wanna look at replacing. Just the energy saving will help offset the cost.

Hello,Make sure the flame sensor is clean near the burners, The flame sensor is a metal rod that is on the opposite side of the ignitor. To clean the flame sensor you will need some steel wool, turn off power to the furnace and remove the flame sensor and clean it with the steel wool. After cleaning reinstall it and turn power back on to furnace.

Crank turns, fuel flowing through rubber lines. wont fire at all, did blow glow plug fuse when driving along, would fire up and then stall, now wont fire at all with fuse rplaced.


if the fuse blew to the heaters then its obvious the wire from the relay box to the heaters is shorting somewhere along the line or one of the heaters itself has burnt out on the end causing this short .

Not firing. usually clicking sound until gas fires up.


If the unit has power, then not likely a bad breaker. The clicking sound you hear is the spark ignitor lighting the pilot. If you no longer hear this noise, the most likely cause is the spark control box, about 3 inches wide, 6 inches tall with wires connected to it.
If you provide the model number of the heater, I can send you a troubleshooting chart to determine if the spark control is bad or possibly a themostat or internal safety.
