Recently acquired this grill, but it was used. I’m having trouble getting it past ~350°F, and it takes at least 30 minutes to even reach that temp.
I’ve already replaced the natural gas supply hose and the regulator. At first, I thought it might have been a propane grill converted to natural gas and that the orifices weren’t changed. However, after checking the serial number, it appears to be factory natural gas.
Has anyone run into this before or have ideas on what else I should check?
