On our Discovery the rear furnace works great but the front Furnace will not come on. If I go outside and have the wife turn the thermostat up I can hear a click but nothing works. It worked fine yesterday but today it just stopped. Any ideas? Does anyone know where a fuse would be.

Are they atwoods heaters if so then you can take the 4 screws off the cover and open the black flap, remove the connector and replace it a few times and check to see if fan spins freely

Yes they are. The fan does spin freely. Thanks I will tinker with the connectors. Any other ideas? Thank you for your response.

There is a time delay it has 4 connections and is mounted towards the top of the motor It starts the motor and delays the gas valve so it will clear the chamber check those connections

Ok I have checked all the connections what else could it be?

Check the sail switch. It may be stuck.

If it clicks. Does the fan come on and just blow air (cold). Maybe an bad fan motor. Or it might just have a mud Dober nest in it causing the wheel to be lodged an notable to spin.

Here's a link to a forum file on furnace troubleshooting. Maybe it will help. iRV2 Forums - Files - RV Furnace Troubleshooting

It clicks but the fan does not come on. The fan also spins freely.

You need to find where you are losing the 12 volts to the fan. The idea behind the sail switch is, the fan comes and pushes the sail switch closed. Then 12 volts goes to the gas valve and you have ignition. You will never have any gas without the fan. Take a test light and work backward from the fan until you find where you are losing the 12 volts.

I will try that and see what I can find
