I'm new & don't type well so please bear with me , My blower was not working had someone check that wasn't a tech but managed to hot wire motor to see if it worked , it did . so I called someone who service's hot water sys. & he thought it might be the circuit board but he doesn't know much about hvac . So he ordered new board , removed old & old board was burnt behind relay , changed bd. started furnace , still no blower . I switched the button on therm. to fan & the rest is history another $100 circuit bd for the trash . He is suppose to check with someone but I'm wondering if anyone has any thought's . I myself am a machinist & worked in engineering & am capable of using ohm meter's & I use to Drag race professianally & build motors but hvac is new to me . If anyone can point me in the right direction I would deeply appreciate it I can't afford another $100 bill out the window . Thank's
