Action required
Sensor is shorted. Software disengages heating pads. Acknowledge error
by pressing the ON/OFF button. If error persists, a qualified service
technician should test the sensor.
◾Test the sensor. Detach the sensor from the warmer. Use an Ohm meter
to measure the resistance of the sensor. Check the sensor at 25°C (77°F).
If the reading is 10 KOhm ±1.5 KOhm, replace the display. If the reading
is ±2 KOhm, replace the sensor.
◾Check the wires for integrity. Inspect the connections at the control and
terminal block to ensure proper and secure connections. If necessary,
re-secure the faulty connections.
◾Contact service if error persists.
Sensor is open. Software disengages heating pads. Acknowledge error by
pressing the ON/OFF button. If error persists, a qualified service technician
should test the sensor.
◾Test the sensor. Disconnect the sensor from the warmer control PCB
and use an Ohm meter to measure the resistance of the sensor.
Sensor PR-37140 should measure 10 KOhm ± 1.5 KOhm at 25°C (77°F).
Sensor SN-33541 should measure 100 Ohm ± 10 Ohm at 25°C (77°F).
Replace sensor if measurement is outside of tolerance.
◾Check the wires for integrity. Check for proper and secure connections
at the control and terminal block. If necessary, re-secure the faulty
connections.
◾Contact service if error persists.
The blanket cavity temperature is lower than the set temperature for 90
minutes or longer.
◾Make sure the door is closed.
◾If the cavity is overloaded, redistribute the inventory. Do not exceed the
height of the insert.
◾Test the sensor. Disconnect the sensor from the warmer control PCB
and use an Ohm meter to measure the resistance of the sensor.
Sensor PR-37140 should measure 10 KOhm ± 1.5 KOhm at 25°C (77°F).
Sensor SN-33541 should measure 100 Ohm ± 10 Ohm at 25°C (77°F).
Replace sensor if measurement is outside of tolerance.
◾The sensor reading is above the temperature set-point. Blanket warmer
triggers at 15° over set-point. Fluid warmer triggers at 5° over set-point.
◾The difference between the room temperature and the fluid set-point
temperature must be greater than 11°C (20°F).
◾Contact service if error persists.
