You could check the venter motor by disconnecting the leads to it and powering it directly with some jumpers. Whenever doing such testing be sure to isolate the gas supply. A person can function check a unit component by component, but many things have to happen in a specific sequence so they often cannot simply be jumpered out. I don't want to go into excessive detail on it simply because if I inadvertently omit a detail that's second nature to me, you could easily miss it and the consequences could be bad. When I need a dentist's services I go to one. When someone else needs a licensed, trained journeyman gasfitter they should consider the same.
I've found a number of those units where the fault was actually just a poor connection at a molex connector (multi-pin connection to the motherboard), sometimes at other spots. Sometimes its a bad ground. Etc, etc.
