I have a Quadrafire DVI32 and I'm troubleshooting a problem with the rheostat for the blower. I replaced the snap disc for the blower and in the process I believe I shorted out the rheostat (sparks were a good clue). Now, the blower comes on after the insert gets to 125 deg but it's on high. Is this how this part fails (as a safety precaution)? I can't find the exact part on the internet (842-0370) - is it OK to replace it with SRV7000-194?
