There is a definite problem here with a dead short, honestly I would return the heater to where ever you purchased it from. To be brand new it should be out of the box and plug it in maybe a little programming and instant heat. Hopefully you are not to far away from the purchase place.

Green LED light on circuit board is off. Fuse snaps as soon as you give power. Solution?


The green light being off simply means there's no power, if the fuse is blowing this isn't surprising. If your circuit board looks OK - no burn marks etc I think the most likely culprits are the components that get the mains voltage which are the two fans and the transformer. You tube has videos about checking these components with a multimeter.

I HAVE A 24VOLT TRANSFORMER WERE DOES THE RED WIRE AND THE YELLOW WIRE GO CONNECTED TO THE HEATER BOARD ST9101A 1014 THE MODEL RGDG-075AMGR


Generally the 24VAC terminals are marked on the furnace board. If it is blowing fuses, check for a short circuit in the thermostat wiring. I have found that the short is usually at the condenser unit where the insulation deteriorated. Many times caused by a dog or cat chewing on the wire. To test, remove the thermostat connections at the control board and power up to see if fuse blows. If it doesn't, you found your problem. Good luck.

I have a speed queen sc35md2yu40001washer that keeps blowing the 2amp fuse as soon as I switch on the breaker it is the fuse where the incoming power goes through before it goes to the transformer


Good job tracing the location of the fuses. Now, logically, the transformer is the next thing to check. When power is turned off at the house breaker, remove one of the wires on the output side of the transformer and see what happens when you turn the power back on. If the fuse blows, the transformer is shot and needs to be replaced. If not, go to the next device on the circuit, etc...

Hi, I stupidly turned on my brand new Francis X7 machine without using a transformer (I bought it from the US, used it in Malaysia), and of course, something blew, and it now doesn't work at all. Any...


The machine is made to work with 120 volts and you have plugged this on a 220 volt mains circuit thereby blowing up the fuse, or the power circuit, possible heater and the main controller unit board.
A step down transformer was needed to work this unit safely . Now unless the unit is opened the damage cannot be confirmed but if you are lucky the fuse would ahve blown and saved the rest. if so test it with a new fuse using a 220 to 120 volt convertor.( transformer with good rating)

The 5 amp fuse on the board keeps blowing the transformer smoked i replaced that but it still blows the fuse when i install a new fuse.the contactor buzzes then the fuse blows.


You ahve a short in the low voltage system, thats why the fuse blows and the transformer burned out. Find the short and then replace that fuse and that should solve your problem.

Brand new furnace, transformer opens on primary side. also seems that transformer is hotter than normal. I have checked all componets for short to ground and have replaced control board.


The short is on the 24V side...I would put a 3 amp fuse in series with the Hot 24v line before it gets to the circuit board from the transformer you will have to replace again....have a few spare fuses....after having done that./...turn the power on and call for heat...Observe what happens and what stage of the cycle you're in when the fuse blows...Exhaust fan starts...Ignitor starts to warn up....etc...I need more info...shorts are hard enough to find as it is.......does it blow the fuse immediately...usually it will go through a few stages before you get to the problem piece....Make and Model of the furnace could also be helpful to me
