Hi, how are you? Sorry for the delay getting to your question. I am gonna tell you the trouble shooting procedures from the service guide to check but basically, you need to check all of the intake and exhaust and make sure there is no blockage in either, make sure the wheel and motor for the vent are in good condition and running. If it ran fine with the front cover off, that would indicate an intake issue. Let me know when you are ready and I will go through the list of checks to do. Thanks

Also, the dip switch settings for vent length are a common cause. Also, circuit board issues. Thanks.
