Why does the compressor run continuously on my Helmer Refrigerator?
- D
  Daniel EdwardsAug 23, 2025
  The continuous running of the compressor in your Helmer Refrigerator can be due to several reasons. First, check if the refrigerator setpoint is set too low and adjust it to the appropriate operating range. Also, confirm the control probe is providing accurate temperature readings and is not faulty by verifying its resistance is in the range of 98 ? to 110 ?. Lastly, it's possible the solid-state relay is faulty and needs to be replaced.

Why don't the automatic temperature tests work on my Helmer Refrigerator?
- D
  dmccormickSep 5, 2025
  If the automatic temperature tests are not working on your Helmer Refrigerator, first confirm the alarm setpoints are set at the appropriate values. Test the temperature alarms manually. Test the probe connections and secure the connections if necessary. Also, confirm the probe is providing accurate temperature readings. After that, confirm the probe is reading correctly and calibrate the probe if necessary. Confirm the probe is providing resistance in the range of 98 ? to 110 ?. Replace the probe if necessary. If the issue persists, replace parts with those included in the control board kit, or replace the monitor/control board.

What does it mean when “Probe Failure” is displayed on my Helmer iPR120 monitor?
- A
  Andrea RodriguezSep 3, 2025
  If “Probe Failure” is displayed on the monitor of your Helmer Refrigerator, it could indicate that the temperature probe wiring is an open circuit. Check the continuity of the probe wiring and connections, securing them if necessary. Also, confirm the probe is providing resistance in the range of 86 ? to 110 ?. Replace the probe if necessary.

Why does the High Temperature alarm activate when I open the door of my Helmer Refrigerator?
- H
  Heather RiceSep 1, 2025
  If the High Temperature alarm activates when you open the door of your Helmer Refrigerator, but clears after closing it, consider these possibilities: First, check the product simulation solution level in the bottles and refill them if necessary. Next, check the high-temperature alarm setpoint and adjust it if it's too low. Also, test the primary monitor or secondary probe and replace it if faulty. Check the probe connections and secure them if necessary. If the issue persists, contact Helmer Technical Service.

What causes the condenser alarm to activate in my Helmer Refrigerator?
- P
  Patrick RogersAug 30, 2025
  If the condenser alarm is active in your Helmer Refrigerator, there are several potential causes: First, confirm the alarm setpoint is at the appropriate value. Next, clean the condenser fins if they are dirty. Also, check the condenser grill and clean it if necessary to ensure the compressor is not overheating due to a lack of airflow. Confirm the refrigerator is correctly located. Next, replace the condenser fan motor, if it is faulty. After that, confirm the condenser probe is reading correctly and calibrate the probe if necessary. Test the probe connections and secure the connections if necessary. Finally, test the probe and replace the probe if necessary.

Why is the AC Power Failure alarm active on my Helmer Refrigerator when it's plugged in?
- A
  Ashley ClarkAug 29, 2025
  If the AC Power Failure alarm is active even when your Helmer Refrigerator is connected to power, check the following: First, verify the power at the outlet and repair or use a different outlet if necessary. Next, ensure the power cord is securely connected. Then, check the ON/OFF AC power switch inside the front lower panel, ensuring it is in the ON position and replacing it if faulty. Also, reset or replace the circuit breaker. If the problem continues, contact Helmer Technical Service.

How to stop the Door Open alarm from sporadically activating on my Helmer iPR120 Refrigerator?
- B
  Brandon WestAug 28, 2025
  If the Door Open alarm on your Helmer Refrigerator is activating sporadically, it could be due to several reasons. First, ensure the doors are closing completely by checking the hinge cams for damage and replacing them if necessary. Next, confirm the door gasket seals completely and replace it if needed. Also, test the door switch connections and secure them if necessary. If the issue continues, the door switch or switches may be faulty and need replacement. Finally, check the time delay for the Door Open alarm and adjust it if it's set to zero. If the issue persists, replace parts with those included in the control board kit, or replace the monitor/control board.

Why is the chamber temperature displayed incorrectly on my Helmer iPR120 Refrigerator?
- R
  rosariorobertAug 27, 2025
  An inaccurate temperature display on your Helmer Refrigerator could stem from several causes. Begin by checking the product simulation solution level in the probe bottles and refilling them if necessary. Next, confirm the primary monitor probe is reading correctly and calibrate it if needed. If the issue persists, try resetting the monitoring system. If these steps do not resolve the issue, contact Helmer Technical Service.

What to do if alarms are not audible on Helmer iPR120 Refrigerator?
- B
  Brian FullerAug 25, 2025
  If your Helmer Refrigerator is in an alarm condition but you can't hear the alarms, try these steps: First, reset the unit by turning off both main and battery power, then turning it back on. Next, check if the audible alarms have been muted by pressing the Mute button until the Mute timer shows no time delay. If these steps don't work, the alarm speaker might be faulty and needs replacement. If the issue persists, contact Helmer Technical Service.
