1. There is no automation on the equipment at all. 2. Heater was manufactured 2004 3. I get that the bezels are different SKU's but they use the same wiring harness so in theroy they should be interchangeable shouldn't they?

Guys new to the forum here and need some help on a Laars LT400N-L. I have 2 questions:- 1. The unit will light and run for hours sometimes to get the temperature up but even with setting the dial all the way to the hot side the unit will stop heating at about 90 deg F and then cycle on and off to maintain this temperature. It never errors out. I just replaced the temperature sensor, 135 and 150 limit switches and exhaust limit switch but this had 0 impact on the issue of it not getting hotter than 90 degF. Is the control module faulty? Any help will be great appreciated. 2. One a slightlly differnet topic are the LT and LX bezel with control board interchangeable?
