Suburban 520820 Module Board Review

I have an odd 30Q Country Oven that had a difficult time finding the correct control board. After many hours of research, I am very thankful that this works! The thermostat worked but the initial fan would not turn on. Followed to the controller. Now the oven works great, hopefully it will last longer than the original, 8 years, but now I still know how to fix it! It arrived 3 days after ordering and used a portable heater as a backup!

My Suburban 30k BTU oven turned on the fan and tried to fire 6 times. I checked the sail switch, gas valve and igniter and all had current within recommended limits and would not fire. Eventually I replaced the board in my 1 year old stove that worked on a trip and I was warm again. This board is different from the factory board in my oven (different size and appearance), but it works great in my oven.

The fan didn't work on the land stove. There are many videos on YouTube of people fixing these issues, some of them are fine, but go straight to the Suburban website and download the service manual (NOT the installation manual or owner's manual) for your model. Follow the block diagram to determine if you need this panel, sail switch, or limit switch. My oven did not have to be removed to replace this circuit board, but this may be necessary on some installations.

Wish I could START by swapping the board instead of making it penultimate! That helped! If your Suburban SF-25, 30, 35 oven is running while your fan is still running but you're not getting that "click" followed by heat, THIS is what you need. Few people seem to want to mention to anyone that this board CONTROLS your mechanical gas valve, so you actually have TWO gas valves and if the board fails the fan will still work properly but the gas valve (even if it is correct) won't open! Well…
