Product review (5 stars): Fit my older Viking cooktop perfectly, works like a charm
My Viking VGSU101-4BSS cooktop failed about 2 years ago, I looked into having the manufacturer make a service call and nearly fainted.
So 2 years of using a lighter just sort of happened, kind of like when I woke up this morning as the parent of a teenager.
I finally grew tired of the extra step and did some research, then did some shopping, took a gamble and it paid off well.
My original module was the PA020020, this one is physically identical in every way, all connections are the same, footprint, everything.
Installed and working perfectly, it feels like a luxury to just turn the knob again.
In case it can help someone, here's a brief step by step:
Turn off gas and unplug appliance.
Remove all grates and center caps.
Unscrew brass rings at center of burners (4), I used a piece of hardware called a 'mending plate', it's a thin rectangle of metal that fit into the slots on the brass rings perfectly and allowed me to unscrew them without damage. Be careful, brass is soft and can easily be damaged.
I read online that my cooktop might drop out from underneath once the brass rings were unscrewed, this model won't.
Once the rings are off, very carefully lift the top off of the cooktop, be very careful it will have 4 wires connected to each of the igniters, you must gently disconnect each one and the top will be free, set it aside.
The module is under the metal guard in the center of the tray, 2 screws hold it down, remove them and set screws and cover aside.
The module is secured to the tray by 3 screws, remove them and set aside.
Don't disconnect any wires yet, place the new module next to the existing one, swap one wire at a time, being very careful to make sure each one is labeled the same on either module.
Only make identical connections, double check, then check again.
Once the connections are swapped, remove old module and secure new module in it's place.
Replace cover, redo igniter connections, replace top, screw brass rings into place, hand tight, reassemble center caps and grates.
Plug unit in, turn on gas and cook something.
