I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed a service call for a client who was experiencing a problem with their heating system. Upon arrival, I found that the system was going into a rollout trip. I checked all the rollouts and safeties and found that one specific rollout switch was not performing as it should. I used a five amp fuse to bypass the switch and provided heat to the client for the weekend. I also ran a combustion analysis and found that there were no flaws or safety concerns with the heating exchanger.
