No LED(s) and no fan. AC power input. Ensure that AC power is
connected.
No LED(s) and both fans on. AC input fuse (2A) on control board.
DC output fuse (1A) on control
board.
VCC on control board. (+5VDC and
–5VDC). Replace fuse as necessary.
Replace fuse as necessary.
Replace control board.
LED(s) on and no power
supply fan. AC input fuse (15A) on power
supply.
+13.5VDC at P13 and P14 on
control board.
If Peltier elements are cooling the
heat exchangers. Replace fuse as necessary.
Replace power supply.
Replace fan
Impinger remains at
ambient temperature. Voltage at P13 & P14 Should be at
+13.5VDC
Peltier current draw. Should be
above 6 amps.
Replace power supply
Replace Peltier element.
Thermocouple failure LED is
on. Thermocouple connections TB1 2 &
3. Ensure proper connection.
Replace thermocouple.
Impinger frozen and cooler
indicates ambient
temperature. Thermocouple placement in heat
exchanger block.
Peltier current draw (>6A) for both
elements on that channel. Ensure proper placement.
Replace bad Peltier element.
Impinger does not reach set
temperature, but is below
ready temperature. System loading.
Calibration and set temperature
adjustment. Ensure system loading is not
exceeding cooler capacity.
Adjust as necessary.
Impinger temperature cycles
up and down. Peltier connections on control
board. Ensure a firm connection on
flag connectors on control
board. Ensure system loading
is not exceeding cooler
capacity.
Ready LED does not come
on when impinger is below
7°C. Ready temperature adjustment. Adjust as necessary.
Water carryover in system. Impinger temperature. Should be
below 6°C. Ch2/3 should be
alternating at -7°C. Ensure system loading is not
exceeding cooler capacity.
Slip LED does not come on
(alarm relay/water slip option
installed).*
*Slip light will not be on if no
relay board is installed. Water carryover in system.
Water slip sensor connections. Ensure system loading is not
exceeding cooler capacity.
Ensure that all water slip sensor
connections are made.
Clean tip of sensor.
Replace alarm relay/water slip
board.
Pump does not start. Ready
and slip LED(s) are on
(alarm relay/water slip option
installed). Pump electrical connections. Ensure proper connections.
Replace board.
