Hello,

I have a Rheem Criterion II about 15 years old. Down Draft Furnace
I just replaced the blower motor and it works great. The problem is when I fire up the furnace the blower comes on the ignite r glows and than just when the burners should ignite the system stops? The green lights on the circuit board flash? Then it starts the cycle all over again and never lights the burners? What am I missing?

Thanks for your help

How many flashs?

Look on the blower door and post what it says about the number of flashs

I ran through the procedure and it flashes very rapidly maybe 13 times (It is to fast to count)
I sure appreciate your help

Look on the inside of the blower blower door and post what it says about the number of flashs

There is nothing posted on the blower door?

There should be a paper diagram on the inside of the blower door telling you the blink legend.
