HELLO TO ALL!
I have a 14 yr old RHEEM IMPERIAL 90 plus furnace that is acting up! When it has set for (say over nite) it takes several tries to get the HSI (hot surface ignitor) to glow properly! Now after it warms up this failure goes away?
Resistance of HSI is ok,and 120 volts from IFC board is present at the HSI when it is required in the firing up squence.
Why would it take several tries to get glowing ok for the flame to start and to continue? This IFC board has 5 try lock out! Then it needs to be reset.
Need an answer/fix before the BUFFALO winter sets in?? lol
