  1. Cleaning H50/52 Blowers The condition of the blower motor has a direct affect on the operation of an H50/52 fryer.

  2. The blower is easily removed and cleaned. Four bolts hold it in place.

  3. The wiring must be disconnected.

  4. Once removed from the fryer, the blower must be disassembled.

  5. Oil trapped in the fan causes it to hold dust and debris, which erodes its efficiency.

  6. The squirrel-cage fan is readily cleaned at a sink, however, the motor must be protected from water.

  7. Apply a degreasing cleaner to the fan...

  8. …and to the inlet ports on the motor side of the fan.

  9. The blower housing should also be cleaned with degreaser

  10. Rinse both components, reassemble and reinstall

  11. 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.

  12. 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.

  13. Earlier model H50/52 fryers used a Kooltronics blower, however, the adjustment is the same.

  14. 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.

  15. 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.

  16. Faulty flame readings can result from a dirty flame sensor. The device is easily cleaned with emory paper.
