Mt Vernon AE combustion motor jammed

[Fredward119]

My combustion motor was making noise after my getting ready for winter cleaning. I purchased an OEM and replaced it. Now the stove shows “comb blower jammed “code. Both blowers are getting power but not enough to spin the fan, it’s like a low voltage . I am assuming my power supply is bad. Any one know which plug to test? Voltages or miliamps? Any suggestions?
Thank you

see page 25
Pull the 2 wires at the fan motor using a jumper wire (EG A lamp cord)
plug it in if the fan motor works most likely the board

Thank you, the wires are directly into the motor , there are two plugs one 3 wire the other 4 wire . I have done this with a previous stove and it worked well. I tried it on the old blower , the 3 wire plug it went up in smoke. LOL

The combustion fan motor should have 2 wires a blue one and a white one they are the ones you jump to test the motor

Can not test with lamp cord Mt Vernon AE motors are DC15V.

Test power supply White and Red wires either at power supply or were it connects to control board.
