Rebuilding mpi monitor 41 combustion blower assembly

I have the blower assembly apart. I have a liquid teflon sealer with a maximum temperature of 550 degrees fahrenheit. Will this be enough for the hot air from the combustion burn chamber air temperature, when it circulates through the blower assembly? The ribbon gaskets show leakage , and my best guess is, a suitable temperature sealant in addition to the ribbon gaskets would be fine. Also,I found a bearing without a wavy spring washer. What is the correct description of this part? I will need advice on testing the solenoid ,and, when reassemblying the combustion blower assembly,how to syncronize this. I read that this needed a device to accomplish this. What is the name of the suitable device to syncronize the ignition event in the burn chamber ,if I am understanding this correctly?

Can't get power to the front panel even though power is showing in the wiring of the MPI 41onitor kerosene

It sounds like there may be an issue with the circuit board on your MPI monitor 41 kerosene heater. Based on your description, it appears that you've recently replaced the circuit board, but you're not able to get power to the front panel, despite power showing in the wiring.
There could be multiple reasons for this, and it is essential to investigate further. Here are some things you can check next:
  • Make sure that all connections are secure and properly connected
  • Make sure that the circuit board is the correct one for your heater model
  • Check the wiring, it could be loose or damaged
  • Check the fuses, they might have blown
  • Check the thermostat, it could be faulty or not connected properly.
If you have checked all these things and the issue persists, it's best to call for professional help as it may require specialized knowledge and skills to troubleshoot and fix the problem. It's important to note that working on heating appliances can be dangerous, and only qualified and licensed personnel should work on them.
