A month or so ago I replaced the the display because I couldn't see the display. I have a Pitboss 720 classic which is 4 years old. I cooked on it 4 times and I went to use it and it wouldn't ignite. I got ER1 message. I called customer service and they sent me a new temperature probe and I installed it today and it still wouldn't ignite. I think now my igniter is bad. I'm going to call customer service tomorrow. Any help would be appreciated.
