Maytag Neptune Door Lock Fuse Installation
Typical resistance values for the door lock wax motor seem to range from 1900 ohms to 1200 ohms, which makes for approximate currents of between 60 and 100 milliamps, figured for 120 volts. The MAC97 triac (Q6) on the controller board is rated for 600 milliamps. I had elected to use a one-half amp (500 milliamp) fuse to protect the circuit board, but the lowest fuse I had on hand was a 1 amp unit. Since the MAC97 can withstand a much higher PEAK, one-cycle surge current, I believe this to still be a viable proctective value, but will replace it with a lower rated fuse as soon as I can obtain one. |
