Plastic Condensate Pans melting or catching on fire when used with a furnace

John1961

Does anyone have any first hand knowledge of the evolution of plastic condensate pans and issues with them melting? It seems in the late 90's there was a black plastic pan but lately there is a grey almost fiberglass like pan being used. Can anyone share any experience with a furnace that caught on fire because of the melted plastic pan?

I have seen melted and cracked but not any on fire.

I checked unit installed ignitor that was bad then I had a pan fire within 5 minutes. not sure exactly why? is it possible oil from a leaking coil ignited
