Pilot Proving Ignition/Sensing Control Module,24V Without Molex, 511-330-097

Fixed boiler with temps in the single digits, no freeze ups. thank you

Exactly the part I needed to make my boiler reliable again

My boiler was cutting out before it got to temp. HVAC guy couldn't find this part locally for less than $500. You had it for less than $200. Changed it out myself and it's been working perfectly ever since. It arrived quickly and was easy to replace.

If your Weil Mc Clsjn hydronic boiler is inconsistently lighting . If it fires sometimes. But not other times when the thermostat is calling for heat. Then this is the part you need!! I worked for me . It was a mystery and after installing this Pilot proving sensor control The mystery was solved. Easy to install as well !!

Thanks

Simple and effective

I had a boiler problem where main burner wouldnt start half of the time and I thought it was flame sensor that went bad and replaced the whole gas burner assembly but that didnt fix it, then I bought this and replace the control module and that fixed it! Fast shipping on the product as well!

Couple of terminals were rearrange from the old one but clearly labeled Rice was more than it should've been For this very basic module

My old sensor wasn't working. My pilot light would go on, but the burners wouldn't light, just made a loud clicking noise. Disconnected the old ignition sensor, replaced it with this one and my heater has been working smoothly. It took 5 minutes to replace the sensor.

The other part of the boiler problem was insufficient gas. The gas company had to unblock the pipe line.
