Safety first: Allow the charger to cool before opening the enclosure. Components may be hot.

Step 1 – Check ambient conditions: Ensure the charger is not installed in direct sunlight or in a confined, unventilated space. Clear any objects blocking airflow around the unit.
Step 2 – Cool-down: Turn off the charger at the breaker and allow 30–60 minutes for internal components to cool. Restore power and test.
Step 3 – Inspect vents and seals: Clean dust from any ventilation slots using a dry cloth. Do not spray liquids into the charger.
Step 4 – Internal sensor check (advanced): With power OFF and cover removed, locate the temperature sensor (often a thermistor attached to the power module or heatsink). Ensure it is firmly attached and its wiring is intact.
Step 5 – Thermal paste / heatsink: If a power module or rectifier is loose on its heatsink, or thermal compound is dried out, a technician should refit or replace the module according to Jaguar specifications.
Escalate: Persistent E07 in normal ambient conditions suggests a faulty sensor or power module; contact an EVSE technician.

Charger shows E07 and will not start; often occurs after a power outage or surge.
