Hi folks -
I am having the same issues with a MasterTemp 400 blower not coming on and a service heater light on.
The AFS light is on but goes away when I blow into the air flow pressure switch tube so I think the board is functioning properly. I can also hear the click on the board for the relays kicking on power. The fan spins freely by hand.
With the multimeter attached to the power going to the motor I get ~13.8v on red / black before the heater relay turns on and 240v after the relay turns on.
below are my test results:
BK to Y = no read on multimeter
R to BL = no read on multimeter
C1 to BK = 26.8 ohms
C1 to Y = no read on multimeter
C1 to W = 27.0 ohms
C2 to BK = no read on multimeter
C2 to Y = 0.1 ohms
C2 to W = no read on multimeter
C1 to C2 = no read on multimeter
Continuity:
G to any (BK, Y, W, R, BL, W) = none
Cap = 8.3uF
Does this indicate the motor is bad? And if so, can I have the motor rewound / fixed or buy just the motor and not the full $650 blower assembly?
