俺家的gas furnace的thermostat突然不工作了。显示屏没有显示。
偶以为是电池问题,就买了新的换上,结果没用。这可怎么办啊
型号是aube th144
那是因为你换了以后需要reset一下,新电池才工作,所以有个缓冲或延迟
Can you see red light through the little circle glass on the bottom panel of the furnace? If there is no light , the most chance is fuse in furnace is broken.
And when you change the thermostat by yourself, make sure the switch is turned off.
