INTERMITTENT OVER TEMPERATURE<br />
Recurring over-temperature alarms can be caused by a bad bimetal. A bimetal<br />
that opens too soon can lead to frost build up that restricts airflow between the FC<br />
& the RC.<br />
Restricted airflow between the FC & the RC can lead to an RC that is too warm<br />
and an FC that is too cold.<br />
A sticking baffle can cause this same situation.<br />
• Associated with a hot or yellowed mullion, a condenser fan could be failing and<br />
causing intermittent over temperature.<br />
The condenser fan motors sometimes develop “a bad spot” such that—if the blades<br />
stop in that position—the motor has trouble starting. A push start (or even vibration<br />
perhaps) could get the fan going. The condenser fans that have this issue have<br />
metal blades. If a unit may have this problem and has a condenser fan with metal<br />
blades, replace the condenser fan with service kit W10181323.<br />
A<strong>UD</strong>IBLE ALARM (LOCATED ON THE USER INTERFACE)<br />

BIR SxS models have audible and visual alert signals to indicate:<br />
-Door Open<br />
-Over Temperature<br />
-Call Service<br />
The reset turns off the audible alarm.<br />
The piezo will be disabled for that alarm condition until power or cooling is turned<br />
off and then on again.<br />
The piezo is always disabled for bottom mounts.<br />
