| Problem |
Possible Cause & Solution |
|
Sealer
will not operate even though fuses are OK and power is connected to
machine (i.e. neither drive motor nor cooling fan will turn on) |
Loose
Set Screw on Rotary Safety Interlock: Check set screw on safety
interlock (for '97 and '98 machines). The rotary interlock switch is
sensitive and will not function if set screw connecting it to the Door
Closer Arm becomes loose.
Solution: Reposition switch shaft and
tighten screw. Machine should stop when door is open, & operate
when door is closed. |
|
One
heat element does not get hot |
Heating
Element wires may be loose or element is burned out.
Check
connections at temperature controller. If both are tight, disconnect
and check for continuity across heat element wires.
Solution: If no continuity, replace Heater
Harness Assembly. |
|
Neither
heat element gets hot in a pair of two (i.e.
Zone #1 or Zone #2) |
Temperature
controller may be broken.
Solution: Refer to Temperature controller
manual and replace if necessary. |
|
"E-7"
error code displayed on Temperature controller |
Thermocouple
wires are loose or broken. Check thermocouple wires at
temperature controller. Make sure connections are tight. If they are and
"E-7" error still appears, detach wires from temperature
controller and check for continuity across thermocouple wires.
Solution: If no continuity, replace
thermocouple (i.e. Heater Harness Assembly) |
|
Motor
will not operate (or operates intermittently) and Fuses
#1 & #2 Blow frequently. Motor controller may display odd
message and/or no message. |
Possible
short circuit in motor controller. Remove fuses 1 & 2.
Check resistance across terminals 7 & 8. Resistance should be
high. If resistance is 0, then there is a short in the motor
controller. Also, should have 8-20 ohm resistance across terminals
10 & 11, 10 & 12, and 11 & 12, otherwise there is likely a
short circuit in the motor controller.
Solution: Replace motor controller module. |
