How might i get schematics/manual/parts?

(eg, I think I need a new fan)

Look around inside, you should find a wiring diagram. (If there is a control board you will not find a schematic for it but they are usually fairly straight forward.) In heat mode there are typically two scenarios for turning on the fan. Either based on a temp sensor placed near the heat exchanger or a basic timer circuit. Both typically use a relay to handle the higher fan voltage/current. Sometimes you can hear the relay click on if you pay attention after gas ignition. Use a vom to check for power at the fan leads to figure out if you have a control problem or a bad fan motor. If the fan motor does not come on the gas should shutdown shortly due to an overtemp situation.

Hi,
If blower motor is older style PSC motor, first thing to check is
capacitor. Is the motor dead or humming or jerking trying to turn?
Is it getting power?
