90% of the time in the Control Panel gives you a code Flah then probably the problem. Most technicians
Diagnose exactly what the board of control, which is the problem. I would like to start with Elimite No switch and if this is not the problem, then go from there. There are many places that you Ofer technical suport and install part alsso find the problem. This page is www.phoenixairsuply.com
This is my side, but you can try others if you wish.
Call a repairman from the oven and let me tell you.
You searched for a professional before you try to use it.
Hello, The limit switch, a safety device for your heater. It works by monitoring the operation of the heating system and if these exceeded, then opens or closes, said the control board that the limit was exceeded. The most common problem usually limiting the "high limit switch, which" monitors the temperature around the heat exchanger, where usually over 180 ยบ C, leading to failure to appear on the panel. This does not mean that the limit is broken, but that is something else is causing the temperature limit is exceeded, the most often is a poor airflow through the filter air generator, often dirty or broken even, a blower fan motor. That's what you want to see, first, before the border. Most high-end switches will be restored as soon as they are cool, but sometimes you have to show only that remain, when they were exposed repeatedly to high temperatures at this time, if no reset should also replace the line exactly the same way aF temperature range. Good luck.
