arrived, stated Convection Oven unit not working properly, flame starts then goes out several times. checked over unit, removed front cover, had to drill out and grind out screws to remove cover. inspect module, disassemble and inspect solder joints on module, OK. inspect flame sensor. check micro amps off sensor. 2.6 micro amps, OK. check gas pressure, was slightly low, did adjust up. unit is operational at this time. could be a module failing. informed customer to let us know if issue returns, then we will need to order module.
