I have a White Rodgers 50A50-241.
When heat is called for, blower turns on, ignitor turns on and blower runs for a couple of minutes.

Blower then shuts off. The red light blinks 4 times. I notice a faint burnt smell from the vents.

Anything I can try? Any suggestions...

Brr! Thank you...

look on back of the blower door & find the code. I guess you are talking about the vent motor & not the blower motor. Blower motor may not be comming on & the unit is shutting doun on high limit. If this is the case you might check the capicator on the blower motor

It's the vent motor. Sorry Kenmac, my bad...
When the blower turns on, it runs very slow. I can barely get an air from the vents.

Anything I need to check?

Check / replace your return air filter, Motor could be going bad . Check capicator as well. When you say blower. I'm thinking blower motor & not exhaust vent motor

Confirmed capacitor is the culprit . MM shows it's shorted.
BTW, it's 97F9002.

Hope this didn't fuse the motor. Will replace cap and post.

Air filter is good...

Just replaced. Works like a charm! :)

4 flashing Red lights on White Rodgers 50A50-241
Slow rotating fan
Probable cause - Capacitor

Thank you Kenmac!
