Ok called the dealer yesterday and they suggested checking duct connections. My furnace is located under the dinette bench. All connections were in place. Might be a breach somewhere else.
New problem, last night, furnace stopped working altogether. Thermostat is set to 75 and wouldn't come on. I reset and it turned on but is not blowing hot air. Checked propane and still full. Help, we're freezing and it's our first trip out. Furnace is a Suburban. Thx.
