| CoolTrol® Alarm Diagnosis
High Temperature
A high temperature can be caused by many different problems. The first step is to check for noticeable issues. Ask yourself the following questions and then apply the appropriate solution:
Cause
|
|
Are your cooler doors open? |
|
|
Solution
|
|
|
|
|
|
|
Have you received a warm product delivery recently? |
|
|
|
|
Give cooler a little more time to bring product down to temp, |
|
|
|
|
|
|
|
Is a warm product placed close to the “Room Sensor”? |
|
|
|
|
Move warm product away from “Room Sensor.” |
|
|
|
|
|
|
|
Are the fans and compressor running? |
|
|
|
|
Make sure all service switches and or circuit breakers are ON. |
|
|
|
|
|
|
|
Have you verified CoolTrol temperatures with a reliable, separate thermometer at the same spot in the cooler/freezer were the ‘Room Sensor’ is located? |
|
|
|
|
IF the CoolTrol temperature reads significantly higher than your separate thermometer, CALL NRM. |
|
|
|
|
After applying the above solutions, the cooler/freezer should return to normal operating temperature in about 30-45 minutes. The alarm will stop automatically when the room temperature lowers.
IF the high temperature still exists, proceed with the following steps:
1) Make a note of the current temp in cooler/freezer.
2) Put CoolTrol into Bypass.
3) Let cooler/freezer run for 30 minutes.
4) Take note of temperature now.
5) If temperature has dropped to operating range, then there may be a CoolTrol
Control problem. CALL NRM.
6) If temperature has risen or not dropped then there may be a refrigeration problem.
