- Propane Supply: Verify that the propane tank isn’t empty. A low supply may disrupt the ignition sequence.
- Electrical Connections: Inspect all electrical connections for tightness. Loose wires can interrupt the power supply and prevent ignition.
Heating Issues
Inconsistent heating can lead to discomfort. If the Atwood 8500 furnace struggles to maintain temperature, consider these points:
- Blocked Vents: Check that all air vents are unobstructed. Debris blocking the vents can restrict airflow and affect heating.
- Clogged Filters: Dirty filters reduce efficiency. Replace or clean filters regularly to ensure optimal air circulation.
- Faulty Thermostat: A malfunctioning thermostat might misread the temperature. Test its accuracy and replace it if needed.
- Inadequate Insulation: Poor insulation can lead to heat loss. Assess your RV or mobile home for proper insulation.
Noise Concerns
Unusual noises can indicate underlying issues. If you hear strange sounds, investigate as follows:
- Rattling Noises: Loose components could cause rattling. Inspect the furnace’s exterior and tighten any loose screws or brackets.
- Humming Noises: A constant humming may suggest issues with the blower motor. Check its operation and replace it if it doesn’t function smoothly.
- Clicking Sounds: Excessive clicking during ignition could indicate ignition failure. Follow ignition troubleshooting steps to resolve this.
- Banging Noises: Banging sounds might suggest that parts are shifting or an internal blockage exists. Evaluate the furnace internally for objects that might be obstructing movement.
Addressing these common issues allows you to keep your Atwood 8500 furnace operating efficiently, ensuring warmth during colder months.
Step-By-Step Troubleshooting Guide
This guide helps you effectively troubleshoot the Atwood 8500 furnace. Follow these steps to address common issues.
Checking Power Supply
- Inspect the Circuit Breaker: Ensure that the circuit breaker for the furnace is in the ON position. If it’s tripped, reset it and try starting the furnace again.
