Venter Won't Run
Upon a call for heat, the venter motor should turn on. If it does not, follow these steps:
Verify that UC1 Control has power, LED #6 (Red) should be lit. Verify that LED# 4 (Red) is not flashing. See “LED Flash Descriptions” under the Troubleshooting tab if flashing. Verify RED voltage selection jumper corresponds with interlock voltage (i.e 24V, 115V or “Dry”).
No, LED #6 (Red) is not lit: Check circuit breaker, disconnect switches and wiring.
Yes, LED #6 (Red) is lit: Verify that the interlocked burner is calling for heat, LED #1 (Amber) should be lit.
No, LED #1 (Amber) is not lit: Verify interlock wiring and that thermostat/aquastat is adjusted to call for heat.
Yes, LED #1 (Amber) is lit: Verify Prover safety circuit fault does not exist. If LED #4 (Red) is flashing, count the number of flashes and refer to “LED Flash Descriptions” under the Troubleshooting tab for next step.
If no faults exist, check for 115 VAC across terminals N and MTR.
Voltage present: Confirm Black and White leads from UC1 whip are securely fastened to Venter motor leads. If so, replace Venter motor.
No voltage present: Replace UC1 circuit board part number 950-8804.
