Hi sir:

Please review the electronic control board with thyristor

 

Hii Sir ..which 1?

 

You must look, x electronic board, where is the control x IR.
Look for, loose wires, broken, connector dirty, loose, or edge connector board, oxidize.
And of course test the thyrist ir in electronic board
If You do nota have skill in electronic, look x a good techo or engineer x test, and troubleshooting.
