Hello! Hoping this isn't a stupid question. I'm new here an to electronics, so please bare with me!

I'm wondering if someone can help me figure out why a resistor is burning out on a circuit board for a sunheat electric fireplace?

The light feature wasn't working (all others were) so I took a look and found the burnt resistor. I replaced it, but it burnt again.

My assumption is that failure of a different component is causing this. I searched high and low online, but honestly don't know where to start.

So, any ideas what is causing this? Is the board beyond repair? And should I quit while I'm ahead (I have limited knowledge so if it's a tricky or hazardous fix, I'm doomed)

Thank you all in advance! It's much appreciated.

 

The topmost RH side resistor appears to be burnt?
And right next to it is a semi conductor that says Lamp.!!
Max.

 

Can you flip the board over and take another picture?

What is the number on that component next to the resistor?

What is the model number of the "fireplace"

 

Also what are the part numbers of the top right two semi's?
Max.

 

The number to the right of the resistor is "BT134". To the right of that it says 97A6 vertically.

It's a first generation sunheat fireplace, on the board it says hx, f15, RME=5-B/4K if that's helpful?

Thank you again! I'm absolutely clueless when it comes to this stuff. Your help is SO appreciated! Maybe I can save this

 

What is the 18 pin IC labeled?
Max.

 

It looks like the BT134 might be the culprit and the resistor.
Max.

 

On the top it says "HT46R47" "A828S2817 #N"

 

Thank you SO much!! I will order one to replace it and see if it does the trick!

That is the micro processor.
If you can remove the BT134 you could test it if you have a meter, other wise just try a replacement and a new resistor, are you sure of the value?.
Max.

 

Oh no! Sorry! I must have been looking at the wrong thing. I don't have a meter but will buy a replacement to test it out.
As to the value of the resistor, I'm fairly confident I have the right one. The number under it and the original resistor was so burnt that I couldn't identify it, so I looked at images of this board online and matched the color bands. Hopefully I did it right?

 

The resistor shows it is the gate resistor of the BT134, hopefully it has not damaged the micro, which appears to be firing it direct through the resistor.
