Presto Hot Air Popcorn Popper Blower Disassembly

ID: 6980

Description: So, here it is, Sunday evening and my daughter...

Steps:

1. This is the Hot Air Popper. worked pretty good and has lots of 'miles' on it. We used it often, and it did work well. New one would be about $20 at some major department stores.
2. But hey, I am frugal....

3. This is what it looks like for real. Still in good shape.

4. This is looking toward the top. There are three Phillips screws that need to be removed.
5. Once removed, the black cover that holds the popping chamber can be removed. the popping chamber and the black cover are removed as one piece.

6. The bottom cover is fastened with four screws. Remove those.
7. Once the bottom cover is removed, the blower motor is clearly visible.
8. Where the power cable attaches to the motor, are four diodes. These diodes only allow half-cycle of a full cycle of positive and negative power cycle to reach the motor.
9. The motor only gets current in one direction,allowing it to spin in one direction. After all, we are dealing with AC current here.

10. With the bottom cover off, the hot air assembly will easily slide out. Power connections and temperature control are clearly visible.
11. Use a multimeter to check the switch for continuity.
12. Check the heating element for continuity.

13. The problem that was visible on close inspections with a magnifying glass, was a charred diode.
14. removed the diode (it was attached by point-to-point soldering to the other ones) by de-soldering.
15. Replace the faulty diode. Description on the diode was V81 N4001.
