Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If the exhaust is clogged you may have to take the exahust piping apart to clean it out. First check where the exhaust terminates for a blockage if it's accessible.
