6-10 Regeneration Heater Replacement Procedure

Dryer models 350 through 2100 Dryers have four or eight three-phase regeneration heaters wired in the wye formation mounted in the insulated box directly above the lower valve.

WARNING! WARNING! Disconnect and lock out power before heater replacement.

1.Access the regeneration heaters from the rear of the dryer. Remove the cover plate secured by two bolts.

3.Sketch the heater wiring configuration so the heaters may be re-assembled properly. Also, note that the loops of the heaters are vertical to prevent drooping when hot.

4.Remove the jumper wires for the heater(s) being removed and/or replaced.

5.Remove the four bolts securing each heater's 3 1/2" mounting plate. Slide out the heater, taking care to not damage the gasketing.

6.Re-install the new heaters in reverse order. Be sure their loops are vertical, like the original heaters were. Securely tighten all fasteners.

Caution!

Caution! The heater loops should not touch each other. This will create "hot

 

spots" and lead to premature heater failure.

7.Re-install the jumper wires according to the sketch made earlier.

8.Re-secure the regeneration heater access cover.
