Many diesel heater problems aren’t due to failure or the need for servicing. Common issues include contaminated fuel, wasp nests in the exhaust, flat batteries, and other external factors.
Step 1: Basic Troubleshooting
Before assuming a major fault, check out our Diesel Heater Fault Finding Page and follow the suggested steps to try getting your heater running again.
Step 2: If the Heater Still Won’t Start
If basic troubleshooting doesn’t work, or you’ve identified a component failure, you have two options:
Option 1: Send Your Heater to Dieselheat for Repair
- Use Australia Post to send us the heater (see our servicing information and service submission form).
