Stuck on a job? Here’s how to get a useful second set of eyes.

Welcome to Tech help. HVAC, refrigeration, electrical, and controls questions all belong here. Start your own discussion with the symptom, the equipment and application, and what you have already checked. Add measurements with units and the conditions when you took them. A photo can save a lot of back-and-forth. You do not need a perfect question. If you are answering, explain what you would check and why. If a suggestion depends on conditions we do not know, say so. When you find the cause, come back and share what worked. That makes your thread useful to the next tech.
