Hi, I have a Train XL90. I have a White rogers ignighter. Model 50E47-060. The other night we woke up and the house was at 64 degrees. I went down to the furnace and found the white rogers box had a blinking light on it. I turned off the power and waited a minute. Then I turned the power back on and after three attempts the burns lit and stay on. Today I am having the same problem but the flame will not stay lit at all. I noticed that on the white rogers box is a tag that states "if the led stays on the unit needs to be replaced." The light in this case does not stay on but blinks. Does anybody have any ideas? I make sure that the exhaust is clear.

Thanks in advance.

Pat
