…and to the inlet ports on the motor side of the fan.
The blower housing should also be cleaned with degreaser
Rinse both components, reassemble and reinstall
The condition of the blower affects the quality of the flame and the quality of the flame is measured by the fryer. A poor flame can lead to ignition failures. The flame should be adjusted to produce a rich orange burn.
Air enters the blower through adjustable vanes on the side. A rich orange flame can be achieved by adjusting the vane and watching the flame change from blue to orange.
Earlier model H50/52 fryers used a Kooltronics blower, however, the adjustment is the same.
The current produced by the flame is also an indicator of the quality of the burn. An AC signal from the module is grounded by the flame, producing measurable microamps.
A meter capable of reading microamps is placed in series in the spark module with the common lead to the ignitor terminal and the red connected to the white lead from the ignition module. With the fryer out of melt and in full burn, the microamps should rise from 3.5 to 6.5 uA in about a minute.
Faulty flame readings can result from a dirty flame sensor. The device is easily cleaned with emory paper.
