Does this pop-up knob include the spring? i.e. once installed, does it pop-up or not.
Answer Hello Russell,
This knob 7739P122-60 has a spring inside it to cause the pop up action. Once installed on the switch, this knob will pop up if unobstructed.
I would like to replace the knob but the whole fan knob unit had gone inside. I believe I have to lift up the top in order to gain access to the fan knob unit but I am having a hard time trying to lift up the top. Is there a way to lift it up?
Answer Hello Tim,
Discontinue power to the unit and verify that the power has in fact been turned off. This will prevent the possibility of electrocution. Disconnect the downdraft duct under the unit to allow the unit to be pulled up. Place towels on either side of the unit folded to prevent damage to the counter top. Now lift the unit and turn it diagonal to the counter top opening and allow it to rest there. Remove the screws around the edges of the cook top and around the inside of the vent area. The top should raise up at this point.
