If you feel that your refrigerated merchandiser is not operating properly, please review the following list before
placing a service call:
Troubleshooting Check List
1.
Is the refrigerator in a defrost cycle? Refrigerators periodically go into defrost cycles. During a defrost
cycle, the refrigerator thermometer may read above 45
F. The thermometer provided with the
refrigerator measures the air temperature in the back of the case. This is only the air temperature; the
product temperature will remain below 45
F when the case is operating properly. Wait an hour and
return to the merchandiser to recheck the temperature.
2.
Do the store conditions exceed 75° F / 55% relative humidity? Killion Type 1 Refrigerated Display Cases
are not designed to operate in conditions exceeding 75° F / 55% relative humidity.
3.
Has the compressor stopped running for an extended period of time? The most common cause is high
pressure triggering the high pressure safety switch. This can happen when the condensing coil, or the
intake filters to the condensing coil, are dirty. Clean the condensing coil or replace any dirty intake
filters. Have a qualified technician locate and reset the high pressure safety switch and restart the case.
4.
Is there at least four feet (48”) between the top of the merchandiser and the store’s ceiling? Top-
mounted condensing units need this space to properly vent the heat they create. Nothing can be
stacked on top of the case, as this also will interfere with proper ventilation.
5.
Are external sources such as heaters, sunrays, drafts, hot tables, etc. introducing heat into the case?
Move these external sources away from the refrigerated merchandiser or move the merchandiser away
from these sources.
6.
Is the return air grill on the front of the bottom deck blocked with dust or product? Remove all product
and dust from the return air grill to ensure proper airflow.
7.
Is there too much product loaded into the case that it is blocking the air flow from the back of the unit?
The load limits outlined in the Product Stocking / Load Limits section of this manual must be followed.
8.
Is the case leaking water? Make sure the condensate pumps are operating properly. Verify that all the
drain lines are clear to freely transfer water.
9.
Is the case too warm? Change the setting switch in the top front of the case (in the compressor area)
to the “Summer” setting for a cooler temperature.
10.
Is the case too cold? Change the setting switch in the top front of the case (in the compressor area) to
the “Winter” setting for a warmer temperature.
