D 4: Heating Capacity Report
This section reports the present status of the heating system.
The controller examines a history of heat-up data and determines
whether or not the heating system is operating normally. The “Heat
Capacity” is said to be bad only if the most recent heat-up failed to
meet the expected heat-up rate and three of the last four heat-ups also
failed to achieve the expected rate. That is, a single slow heat-up will
not trigger a “Slow Heat” warning. The Slow Heat warning is activated
only after repeated low-rate heat-ups is observed.
The controller can’t assess the integrity of the heating system if the fryer
has been experiencing voltage problems. Low heat rates observed in
this situation might be due to voltage problems rather than heater
problems.
