When powered by an external 5V wall adapter the motor does spin so it seems the motor just isn't powered appropriately, the connector doesn't seem to be the problem either as the reading head shares the connector to the main board

Hey Cameron,
I saw you post today on another forum and did not have time to put my thoughts down before work. I agree not a clutch issue I had to :), you would be so lucky. I own the machine and can’t offer any more troubleshooting then what you have done, good job of that. Unfortunately the FAV6800AW/FAV9800AW SM doesn’t have a whole lot of support for troubleshooting beyond what you have done for this issue. I found more info from the MAH3000 manual on the technical operation of the motor controller (slightly different controller). Both machines use the same troubleshooting paths. Remove JP4 which is;
P1 Motor Control common
P2 Torque (to Motor Controller) see page 1-11 MAH3000
P3 Motor Control Tach (to control board input)
My WAG is replace the Motor Controller 1st, then Control board 2nd and a possible tach issue related to the motor. That’s enough WAGing,…. but with troubleshooting not a complete WAG :).
Take a look at pages 2-5 thru 2-11, I keyed in on page 2-11 in the MAH3000, it may give you some additional insight, I know we are dealing with different machine designs but I think the designs are close regarding motor controller, the motor and what the Control Board is doing and looking for with input from the Motor Controller. I wish the FAV6800AW/FAV9800AW SM gave this kind of detail for troubleshooting. There is a nice little troubleshooting table on 2-11.
I keyed in on this note;
The motor control monitors the signals and communicates this information to the machine control (control board). The purpose of this signal is to tell the motor when to energize each winding in the motor and to tell the machine control the actual motor speed.
Then this note;
Note: If the machine control board does not receive an input signal from the motor control/tachometer circuit (JP4 connector), the motor speed will rapidly accelerate for 5 seconds then shut down. The machine control will sense a "locked rotor" condition and the motor will stop. If the motor control does not receive an input signal from the motor, the motor will "****" for 5 seconds then shut down.
I don’t believe you have that condition. I have worked with a forum member who had an issue with the motor controller related to an Lr error, locked rotor error and replacing the Motor Controller fixed the issue. Form here I vote for an issue with the Motor Controller. Not having known good parts makes this a difficult job.
The control board is under warranty for 5 yrs from DOP, the Control Board is 2 yrs. Ebay is a good source 25001079
I would push Maytag CSV for both. I got them to send me a Control Board after discussing my troubleshooting and that I had a neighbor (me) that was a repair tech who would install. I also had to send them copy of my warranty not sure why they beeded that my machine was on file with them.
In your console you will find a Troubleshooting guide if you haven’t pulled it out already. It has the schematic for the machine which I find handy. If you want a soft PDF copy of the schematic I can e-mail you. Just ping me at [email protected]. I use that for one-way contact, just respond back on this post if you ping me, I don’t check the account for month’s at a time.
With my limited knowledge I will try to help you. Good luck. Rich

Should not be a problem, the theory here is Volts * Amps =Watts
5V * 2A = 10w
The alternative is to get a LM7505 ($1 or 2) from radioshack or any electronic supply and regulate the 12v down to 5v. its about 1/2 square IC chip.
Pardon my ASCII:
[_]
input 1.7V - 35V ________| | |_____ +5v (+/- 1%)
Pin 1 Pin 3
will accomodate 1 Amp (1.25 if heat sinked) for the CMOS version, slightly higher for the olde r(less effecient) version
The other pin is ground. OF course you will want to check the specs and pin assignment for the brand you buy, these are typical.

Most likely it is the thermostat. It may also be the motor, but usually you will hear humming of some sort. There is a small thermostat on the blower housing that usually goes bad and presents the situation listed.
