Diagnosis was that the PCB was not applying power to hold the propane valve open after the pilot was released. To replace the PCB you:
1. Remove the cover under the heater base. (2 screws)
2. Unplug all PCB connections
3. Wedge a pocket sized straight slot screwdriver between the PCB edge and the edge retaining lip, then pry the PCB out of its retainer.
4. Place one edge of the new PCB under one retainer lip and carefully snap the opposing edge under the opposing lip.
5. Plug in PCB connectors and refasten the heater base cover.

1. Remove 2 phillips screws from bottom plastic cover of heater and remove cover.
2. Remove 1 Phillips screw from old pcb board: match it to new pcb board to insure correct replacement part.
3. Pry wiring harness off old pcb board with small screwdriver.
4. Pry old pcb board out of plastic retaining clips with small s crewdriver.
5. Install new pcb board and bottom plastic cover in reverse order.

NOTE: The new pcb board fixed the problem, and thus the new \"multi bracket assembly\" (thermocoupling) was not needed or used; but I kept it as a back-up for possible future need/use while parts for this heater are still available.

The heater stayed lit after releasing the pilot knob after installing this pcb board.

My heater wouldn\'t stay lit. I thought it was the thermal switch, but also purchased the PCB, as many suggested might also be the problem. I\'m glad I did because I ended up needing it.

Pilot wouldn\'t stay lit no matter how long you held the knob in. It stopped every time the knob was released.
