TROUBLESHOOTING
Symptom
Possible Solution
Unit has power but
the Seal Plate does
not work
Does the Red Indicator Light turn ON when the unit is cycled?
1) If neither the Light nor Seal Plate work, verify that the 25 Amp fuse is good.
2) If the fuse is blown, verify there are no shorts to ground in the unit by checking wiring and
connections (see Figure 1).
Verify the Switch located in the Rocker Arm Assembly is functional.
1)Listen for an audible “click” of the Switch as the Seal Plate is pressed down.
Verify that the Pivot Bolts on the Rocker Housing are not too tight and that the Rocker
Housing rotates freely.
NOTE:
The Pivot Bolts are installed with thread lock compound and tightened to
leave a 0.015” gap between the bolt head and the Rocker Housing. If the bolts are re-
moved this process must be duplicated.
Verify that the bolts on the rear of the Rocker Housing that mount the switch are tight
and that the Switch is contacting the metal Base appropriately.
2) Verify switch wiring is intact by isolating the unit from power and using volt-ohm meter set to
measure resistance, measure between points A and B while cycling the Seal Plate. You
should see the circuit open and close as the Seal Plate is cycled up and down. (see Fig-
ure 1)
3) Replace Seal Plate & Rocker Arm Assembly or make repairs as required
(Seal Plate & Rocker Arm Kit - 625ES Part #6340-078; 107ES Part #6135-038;
Verify the Timer Board is working properly. Upon actuation of the Seal Plate the sequence of events
should be as follows:
1) The Red Indicator Light should illuminate at the same time that the Seal Plate begins to get
hot.
2) The Seal Plate Timer should make an audible “click” and remove power from the Seal Plate
in 4 seconds or less (depending on the latent temperature of the Seal Plate).
3) The Red Indicator Light Timer should remove power from the Red Indicator Light after a
fixed time of either 3 or 4 seconds (depending on the Time Selection Switch setting).
If any of the previous steps do not occur, verify that the individual timers are seated properly to
Inspect and verify all wiring connections and condition of wires. (see Figure 1) Repair as required.
If the plate does not heat at all or is only slightly warm to the touch, replace the Seal Plate & Rocker
Arm Assembly (Seal Plate & Rocker Arm Kit - 625ES Part #6340-078; 107ES Part #6135-038).
Film Cut-off Rod
does not work at
all.
Verify the unit is plugged into a 20 Amp, GFCI circuit and the Power Switch is set to the “ON” posi-
tion.
Verify that the 1 Amp fuse is good. If the fuse is blown, verify there are no shorts to ground in the
unit by checking wiring and connections. Replace fuse as required (Part #1821-034).
Clean Cut-off Rod surface and verify it is not bent. See “Cut-Off Rod” Maintenance.
Film cuts too slowly
Replace Cut-off Rod Control Board (Part #1818-001)
Replace Cut-off Rod (Part #6340-062)
