Chamber won't heat up:
1. Verify top and side panels and insulation are installed.
2. Verify chamber fans are operating.
3. Check J3 heater connector/pins on the PDB.
4. Heater bad. Check heater resistance - should be 36 +/- 5 ohms.
5. Relay failed on PDB, replace PDB.
Head won't heat up.
1. Low AC input power. Make sure system is NOT attached to an ext. cord/power
strip
2. Fuse on the 120 VDC supply is blown (on PDB).
3. Umbilical cable connector loose at head board - check to make sure it is fully
seated.
4. Verify 120 VDC at head heater connectors, if present check resistance of
heaters 92 Ohms. If heaters are out of spec, replace toggle head.
5. T/C board is bad. Replace T/C board
6. Head Board is bad. Replace Head Board
7. Check for 120VDC output from the PDB. If voltage is not present or low -
replace the PDB.
8. Check ground between Toggle Plate and Head Board. If open, check for
missing washers on head.
9. The heater wires in the umbilical cable are broken
10. Replace toggle head
No fans, lights, text and no LCD
back light (no nothing)

2. Verify circuit breaker is in the ON position
3. Check if the thermal snap switches are open. If snap switches are open, verify
chamber fans are operating correctly. Replace chamber fans.
4. 24VDC power supply is bad. Replace 24VDC supply.
5. Check cable from 24VDC supply to PDB.
6. PDB has failed, no 24 volt output. Replace PDB.
No fans, lights, text and LCD
back light is ON
1. Check .cfg File for additional error codes (root cause).
2. Check 24VDC at power distribution board, if not present replace 24 VDC
supply.
System won't boot, no display
after 5 minutes.
- Fans, lights and LCD
backlight are operating
NOTE: Replacement Hard Drive
may take up to 45 minutes to

1. If system homes: Check LCD cable, if OK replace LCD
2. Re-seat the I/O card.
3. If system does NOT home: Power on for at least 10 minutes. If still no text, Cycle
power at circuit breaker and wait 10 minutes. If after three power cycles of 10
minutes each and there is still no text replace the hard drive.
4. Measure for 12VDC at the hard drive. If not present check 12VDC power
supply, replace cable or supply as needed.
5. Replace SBC to hard drive ribbon cable.
6. Replace SBC.
System powers off after a few
seconds.
1. Check for shorts in the AC input. (eg. circuit breaker, line filter board, AC input
cabling)
2. Power switch is bad, replace power switch.
3. Verify DC power supply outputs are not shorted to ground.
System reaching temp, does
not go to “Idle” screen and
head hits into the right side of
