Had issue with the burner not staying lit on the boiler which resulted in no heat. Had a service person come to the house and he said that the aquastat was bad and gave a quote of over $1000.00 to fix it. Well looked around and found this exact replacement for the bad one on the boiler. Read the install directions and change out was very easy. Adjusted the high temp cutoff to be the same as the old one that was removed, hooked up the wiring and was good to go. Heating system works as it should. Saved close to $800.00 DIY!!
