With each season’s change, it can take a little time for technicians to adjust. It seems every summer we forget all about how heating systems work and every winter we purge the concept of the cooling cycle from our consciousness. Therefore, the first few weeks become an adjustment period where it requires extra focus to remember the fundamentals of gas pressure, temperature rise, sequence of operation, flame rectification, etc.
Recently, I have spoken with quite a few technicians and company owners on the topic of furnace short cycling.
As cold weather approaches and heating season enters, HVAC professionals might see an increase in service calls from customers who say that their heat has stopped working or won’t turn on. One of the most common problems identified is heat sequencer failure.
Several issues can contribute to the failure of this part:
As the summer heat slowly begins to fade, the cool breeze of fall will meander into the area. Many of us will begin to shift our focus to heating equipment check-ups. These can be a bit monotonous in the early days of fall, but the most important time to check a heating system is before it endures regular run time through the winter.
