troubleshooting Section

The following troubleshooting guide is designed to help identify and resolve any operational difficulties that may arise with the PP-1808-1812-1816-44-V2. While performing the tests and checks outlined below, carefully inspect the machine for loose components, broken or loose wires, and poor electrical connections. It is essential to check switches, controls, relays, transformers, and other electrical components thoroughly. When diagnosing electrical issues, always use a voltage meter.

Important Notes:

• Use extreme caution to avoid the risk of electrical shock. Only apply power when necessary for voltage checks, and disconnect power immediately when it is not required.
• Always refer to the electrical components placement sheet and schematic diagrams to aid your troubleshooting efforts.
• DISCONNECT ALL POWER BEFORE MAKING ANY REPAIRS.
• Refer to the Electrical Board Layout and Electrical Schematic Diagrams for the precise location of electrical components

Check for 220 volt on wires 8 and 9 on CR2 with CR2 contactor pulled in under set temperature. If voltage is present on CR2 contactor on wires 8 and 9, check the Heat Bank for broken lugs or wire inside the Heater Bank. If leads and jumper wires on Heater Bank are not broken or burned, then replace the Heater Bank.

Check Heater Bank for replacement. Make sure no lugs on the Heater Bank have been broken.

Check the heater bank to make sure the wires are not loose or broken on the heater bank. Pull the
heater bank and make sure the heater bank has continuity across wires. If not, replace it.

If no control over heat, interchange thermocouple wires at temperature controller. If still no control,
check for replacement of CR2 or temperature control.
