Wall furance wont turn on

I have a basic wall furnace that wont turn on. It's a Williams wall furnace models 25-35-50. The pilot is lit and i can feel a small amount of heat coming off it but the thermostat doesn't turn it on (no battery in the thermostat). My landlord is basically refuses to send someone out to fix it because she isn't convinced the problem isn't related to the pilot which apparently can be fixed for free by the power company, however I'm cold and i want my heater to work! I've been told the problem is the pilot generator or the thermocouple. I went to the hardware store to buy a thermocouple and they told me the problem is the pilot generator so i bought one but i honestly have no idea how to replace it. I can't find any instruction online so I'm not sure what to do. Does it sound like the problem is the pilot generator? How hard is this to replace? can i just open up the furnace and figure it out?

on the exsisting pilot flame....is it hitting the old power pilot solidly with its flame,if yes,just install it as you removed the old one and plug the wires in where removed from the old one.set the stat to 50F after installed wait 5 minutes,and set the stat to 70F or higher should lite off.

not that this helps the OP but I've got the same model and problem. I'm looking for a replacement thermocouple. Your landlord fuuucked you. The thermocouple has an electric component that my neighbor tells me aren't used anymore and therefore hard to find. I'll post again when it's fixed for whoever else.
