Currently am a technician for a medical equipment company. I have been repairing a warmer recently over the last few months. Well, several of them. We are the retailer. The controller is a LOVE controller - the nurses just love the name haha.
Anyway - the warmers are supposed to hold 40deg C. They often will be sitting at 24deg C when I go in. I replace this controller, and the fault goes away.
Problem is, I cannot find anything wrong with this controller. Its simple, will bench test fine with a load. And also bench test with a load whilst I am heating the controller itself.
We are supporting this product for several more years. Unsure what can be done to resolve this. Any advice would be great. Oh. Item 13 is a 220/110 transformer.
