is tripped or unit's main power cord is
not installed properly.
2. Check coil on power good relay with
ohm meter. If open electrically replace
relay.

connections to power good relay.
Check low voltage connections going
from relay to main control board.
Check continuity through relay
contacts to ensure proper operation.
Repair any connections as needed.
4. Contact Electro Freeze Technical
Support
1. Test to see if coil voltage is
present at pump control relay, If it
is not and pump is still running, the
control relay is stuck and needs to be
replaced. If coil voltage is present then
control board or Transducer may be
malfunctioning.
2. Attempt to calibrate the Transducer
to 0 psi and re-test unit. If unit
continues to malfunction contact
Electro Freeze Technical Support.
3. Contact Electro Freeze Technical
Support.
