My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If you no longer need help post a simple reply to let me know.My info is somewhat limited on your model here but no one else has responded and would like to see if I can help here since your question has been sitting for so long.If at any time you feel that I cannot help with this please let me know.

If the heat from the exhaust fan is not as hot as it used to be this can be a fault with a lack of fuel to the burners due to a failing flow valve or restriction in the feed lines.You will need to have this checked into to see if this is a fuel flow issue causing this fault here needing cleaned out or repaired.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
