• If 0 ohms (0 Ω) is measured;
• Check RTD (Resistive Temperature Device)
• Check wiring to the RTD (refer to the main panel wiring diagram)
• Check wiring to the HI-LIMIT temperature controller (refer to the dryer Main Panel Wiring
Diagram).
• If RTD (Resistive Temperature Device) measures in the range of 100 ohms (100 Ω);
• Check wiring to the HI-LIMIT Temperature Controller (refer to the dryer Main Panel Wiring
Diagram).
• If wiring checks out;
• Replace the HI-LIMIT Temperature Controller
• Retest
3b) If there is no display on the HI-LIMIT Temperature Controller:
• Check that main power is “ON;” front panel “BLUE” indicator.
• Check that ALL “EMERGENCY STOP” (E-Stop) buttons are disengaged (out).

a) PROBABLE CAUSES;
1a) Stop motion detector module or sensor. With control voltage “ON” (“GREEN” push-button), use the
pendant control in “LOAD POSITION” to rotate the tumbler (basket).
NOTE: Input #0,10 on the RTD (Resistive Temperature Device), stop the tumbler (basket) and wait for
device’s latched relay to de-energize. The time from when the tumbler (basket) stopped to the
relay de-energizing should be 15 to 20 seconds.
• If the de-energizing time is satisfactory, the unit is operating correctly;
• Check circuit wiring, and retest (refer to the dryer Main Panel Wiring Diagram).
