To troubleshoot a door that doesn't open easily on your Helmer Scientific Freezer, start by ensuring the door handle is properly aligned. If the issue persists, check the hinges for any debris and clean them if necessary. Lubricate the pivots in the hinges using a general-purpose grease. Lastly, inspect the hinge cam for damage and replace it if needed.
What does 'Probe Failure' mean on Helmer Scientific i.Series?
If you see a “Probe Failure” message on the monitor of your Helmer Scientific Freezer, first check the continuity of the probe wiring and connections, securing them if necessary. If the wiring is intact, confirm the probe is providing resistance in the range of 86 to 110 ?. If not, replace the probe. As an additional step, test the CP board circuitry by removing the probe connector from the board and placing a jumper across the jumper pins; the display should then show 4 °C +/- 2 °C.
How to stop Door Open alarm activating sporadically on Helmer Scientific Freezer?
If the Door Open alarm on your Helmer Scientific Freezer is activating sporadically, first ensure the door is closing completely and that the hinge cams are not damaged; replace the cams if needed. Also, make sure the door switch is being properly activated by the door switch plate and adjust if necessary. If the issue persists, the door switch itself may be faulty and require replacement. Finally, check the time delay for the Door Open alarm, as setting it to zero will cause the alarm to activate immediately when the door is opened; adjust the time delay as needed.
Why is 'High Temperature' alarm activating sporadically on Helmer Scientific i.Series Freezer?
If the “High Temperature” alarm is sporadically activating on your Helmer Scientific Freezer, make sure the primary monitor probe is fully immersed in the product simulation solution within the probe bottle. Also, verify the upper monitor probe is reading correctly and calibrate it if necessary.
How to stabilize chamber temperature on Helmer Scientific i.Series Freezer?
If the chamber temperature of your Helmer Scientific Freezer does not stabilize at the setpoint, start by checking for obstructions to airflow within the chamber and remove any that are found. Ensure the unit cooler fan is running by checking the voltage to the fan when the door switch is activated, and replace the fan motor or door switch if necessary. Clean the condenser grill if it's dirty. Confirm that the ambient air temperature around the freezer is within the required range. If the evaporator is covered with ice, initiate a defrost cycle. Additionally, check the control probe reading and adjust the offset if necessary, and inspect the probe connections at the CP board. Finally, examine the refrigeration lines for leaks and check the refrigerant level, recharging if needed.
What to do if AC Power Failure alarm is active on Helmer Scientific i.Series?
If your Helmer Scientific Freezer is connected to power but the AC Power Failure alarm is still active, ensure the ON/OFF AC power switch is in the ON position. Verify the power outlet is working correctly, and if faulty, repair it or use a different outlet. Also, check that the power cord is securely connected. If these steps don't resolve the issue, reset or replace the circuit breaker.
Why does the compressor run continuously on my Helmer Scientific i.Series Freezer?
If your Helmer Scientific Freezer's compressor is constantly running, the freezer setpoint might be too low. Check and adjust it to the correct operating range. Also, the control probe might not be reading correctly, so check its reading and adjust the offset if needed. Inspect the probe connections at the CP board. If the issue persists, the solid-state relay may be faulty and require replacement.
