Good
- Carefully re-do this troubleshooting guide steps.
- If no problems were found with the circuit and wiring, replace the electronic refrigerant reduced pressure valve and Go to "Verification Of Repair " procedure.
No Good
- Repair open or short in circuit and then Go to "Verification Of Repair " procedure.
