SPECIFIC ERRORS AND ISSUES
The technically advanced diagnostic capabilities of the 
electronic controls utilized on the 1200 and 2200 series 
units allows for easy and thorough troubleshooting.
Navigation of the control is the key and is explained in the 
CONTROL OPERATION section of the manual, along with 
control button layout, control function descriptions, a 
service mode menu and service menu selection 
explanations.
Verification of temperature and thermistor performance 
can be identified by directly viewing thermistor readings in 
the service mode.
Component failure issues can be identified through service 
mode menu #19, “Component Testing.” Individual 
components can be switched on and off to check for both 
proper function of a specific component and also delivery 
of supply voltage to the components through the relays 
and DC outputs located on the relay/power board.
