RHeem Model RGVH-07EAUER
SN (CY50302?) F1194 6448
Control board Model 1012-920A
Additional number on control board 62-24084-02
1. When Thermostat set to cool -works - unit cycles correctly
2. When Thermostat set to off and fan to on - unit blows
3. When Thermostat set(or turned) to heat - blower shuts off.
3a. Induced draft blower starts - yes
3b. 30sec Prepurge - yes
3c. Igniter warms up 34sec warmup +9for ignition - yes
3d. Main burner lights
3e. Main burner continues to burn
3f. After 20 seconds I hear a click but no blower motor
and I can't even manually override because it won't come on even if i set the fan to ON at the thermostat (if it is set to heat)
I am having a hard time finding out which wire triggers the fan from the heat mode? can anybody give me a terminal to test for power?

Green is the fan and red is your hot at the thermostat if the tech wired it by color code.
One step at a time

The board controls the blower in heat mode.If the blower is not coming on in heat the board is bad.
