How do I know which wire goes to where in infinite switch?
Answer Hello Jay. Look at the old switch. Each terminal has a marking. Usually it is L1, L2, H1, H2, and P. Just match the wires to the same location on the new switch as they were on the old switch.
Which direction do you turn cooktop switches to turn on burner?
Answer Hello Cory. You should be able to turn it either way to turn it on.
I just ordered an infinite switch. I removed wire by wire when I noticed on the old location h1 and h2 is in different location than on the new one and the l2 l1 is the h1 h2 on the new location. Is this the right switch or just but l1 to l1 no matter.
Answer Hello Dewayne,
The manufacturers are always trying to improve the parts on the units and this is a common question. You just have to make sure the wires are connected to the terminals labeled as the old terminals were labeled. It will still work just fine.
I just ordered 2 sets of surface unit switches for our amana range. The original switches are still working but smoke was coming from the larger burner switch. I removed it and noticed it was blackened inside of it., p/n 3148954. and the other large burner's switch was also blackened.
One of the smaller burners had a blackened area inside of it's switch p/n 3148951. So, I ordered replacement switches for all 4. 3149400 (2) and3149404 (2). Now my question: Are both of these switches considered "infinite" switches? The 9400.. is called a surface unit switch, by my receipt. Please let me know if I have ordered the incorrect switches. Also, we have not used this range very much at all, and was concerned as to why the switches are blackening or burning. Was told by a friend that if we did not turn the switch on Exactly on the setting , as putting the know in between settings, that could cause the switch to burn. What's your professional answer.
Answer Hello Jeff,
It appears that you have ordered the correct parts. As for the switches blackening, they are infinite switches. They cycle off and back on by the current flow or by the voltage draw, (depending on the particular design). The blackening is considered normal from breaking and making the of contacts which are located beside where the blackening is occurring. The switch that was smoking probably got some grease into it from normal operation. Your friend is incorrect since the infinite switch has no set contact points for the knob to go to but instead is more like a volume control on a radio. This is similar to a potentiometer in the sense that you can stop the knob at any position.
