White-Rodgers model 50A50-206 Troubleshooting Guide
Anyone know where I can find a copy of Troubleshooting Guide for a White-Rodgers model 50A50-206 hot surface ignition control for my furnace? I checked the White-Rodgers web site, but that model is superseded and they don't have any information on it. The new model they recommend to replace it is quite different and I doubt the info on that one would apply. |

Just buy the replacement, they aren't worth trying to repair.

White-Rodgers model 50A50-206 Troubleshooting Guide
I'm not trying to repair it. It works fine. I just want to know the theory of operation - e.g. what sensors does it test, and in what order. For example: If the ignitor is burnt out (open circuit), does the control detect this and refuse to open the gas valve? Or... does it open the gas valve, and then detect no flame, and turn the valve back off? Stuff like that. |

Almost everything goes through that board. There should be something like a
sequence of operation in your owners manual. Something like "Igniter Lights" - "Yes" or "No". "Bob" wrote in message ... Just buy the replacement, they aren't worth trying to repair.

I guess I wasn't clear. I do not have an "owner's manual". I never got one. I do not know who installed the furnace. Even if I did have an owner's manual, I doubt the information I am seeking would be in there. For example: If the ignitor is burnt out (open circuit), does the control detect this and refuse to open the gas valve? Or... does it open the gas valve, and then detect no flame, and turn the valve back off? Stuff like that. EJ |

Or... does it open the gas valve, and then detect no flame, and turn the valve back off? I only know about stoves, but stoves do it a third way. (There is almost always, in every area of thought, more than two ways.) Ini a stove with a hot surface ignitor, the control supplies power to the ignitor/valve circuit, and when current through the ignitor is sufficient, it allows the valve to open. If the ignitore is burned out (rare, right?) no current flows through the valve becuase it is in series with the ignitor. Maybe furnaces are different. Stuff like that. EJ Remove NOPSAM to email me.

If the igniter doesn't light, the gas valve will not open at all.

If the igniter doesn't light, the gas valve will not open at all That sure sounds like the safe way for it to work. And it seems to agree with what I observed: the igniter was not glowing, and I couldn't smell any gas at all. I do wonder something though. IF the gas were to turn on (but not ignite), would the smell be detectable? Or is the vent motor so effective that all the unburnt gas would be vented and you wouldn't smell it. Just wondering if anyone has any experience with such a situation. EJ |
