Switch the multimeter to continuity mode to test continuity. Connect the multimeter probes to the correct terminals.

2. Checking for continuity across the ignitor terminals                                           

To check for continuity across your furnace ignitor terminals:

• Set your multimeter to continuity or ohms.
• Touch a probe to each ignitor terminal.
• A low resistance measurement or sound indicates ignitor continuity on the multimeter.
• A defective ignitor requires replacement if there is no continuity.

Step 5: Verify proper voltage supply to the ignitor

Check the ignitor’s voltage to guarantee proper operation. Test the voltage supply to confirm it fulfills requirements.

1. Testing the voltage supply to ensure it meets specifications                                          

Measure the ignitor terminal voltage using a multimeter to test the voltage supply. Verify that the measured voltage fits furnace manufacturer requirements.

2. Confirming the presence of adequate power for ignitor operation                                           

Check that the voltage supply fulfills ignitor power requirements. Check the furnace’s user guide or multimeter for the recommended voltage range.

Step 6: Check for spark generation

Check the ignitor for a spark during the furnace’s ignition cycle. This means the ignitor works.

1. Observing the ignitor during the furnace’s ignition cycle                                          

Watch the ignitor for a spark during the furnace’s ignition cycle. The ignitor is working properly and will ignite propane to provide heat.

Reassembling the ignitor assembly securely allows the furnace to be checked to ensure proper functioning.

2. Verifying the generation of a visible spark                                           

Monitor the ignitor throughout the furnace’s ignition cycle to confirm a spark. If the spark is visible, the ignitor is working.

Step 7: Reassemble and test furnace

Reassemble the ignitor tightly to finish. Reassemble the furnace and test the ignitor by lighting it. This checks your furnace’s operation.

1. Reinstalling the ignitor assembly securely                                           

Install the ignitor assembly carefully in the furnace to fix it. All connections should be secure.

2. Testing the furnace operation to ensure proper ignitor functionality

It’s important to maintain a furnace’s ignitor, which starts the heating process. During furnace testing, the ignitor must heat to the right temperature, ignite the gas properly, and maintain a flame to warm the home. Regular checkups prevent cold snaps, keeping homes warm.

Test the furnace performance after securely reassembling your camper RV furnace parts or ignitor component or RV Furnace parts to confirm appropriate operation. Start the furnace and make sure the ignitor sparks and ignites propane. The furnace may need more troubleshooting if it doesn’t ignite.
