Burnham Freedom FCM-120 troubleshooting
I recommended a Burnham Freedom FCM-120 to a customer and now it is showing a "E 29" error code, In the manual it says "E 29" means that the blower fan speed has not returned to zero rpm, and it also says that a miswired fan spped harness or a defective fan could be the possible causes.
The boiler was running fine for the past 10 or so months and now this.
How would I test the fan to see if it is defective?? what else could cause this? has this happened to anyone else?
