Ok the hot wire should pigtail to all 3 switches
All the white wires should tie together with a wire nut
Out of each switch the black to the fan/light /and heater will go
Customer: replied 5 years ago.
Remember there are 2 main wires coming from switch box each has a black and white wire in fan heater blower unit there is a blue and white wire for the light ablack and white wire for the fan and a red and white wire for the heater as of now the light comes on with the light above the sink the fan comes on correctly but when i have the lights on and then turnon the heater the heater works but the light in the unit cuts off light above sink stays on this does not bother me but i cannot figure out correct wiring.

All white wires will go to your incoming white wire

red from heater to heater switch

black from fan to fan switch

blue from light to the light switch

All switches will have the same incoming feed

Customer: replied 5 years ago.

Ok were the switches all jumped togeather before ? as far as the feed goes ?

Is there anything else not workng ?

How do you know these are hot without a meter ?

 

PLEASE answer all 3 questions

Customer: replied 5 years ago.

Switches already jumped together when home was built. Only thing wrong now is when you turn on heater the lights above sink and light in new BROAN model 655 comes on.I do not have a meter but the two wires in attic coming into BROAN unit have to be hot or nothing would work or is only one hot guess i need to get a meter.

2 sets of wires going into the broan ?

Or just 2 wires ?

Customer: replied 5 years ago.
Two sets of wires . Each has a heavy duty white@Black.
Expert:  Glenn replied 5 years ago.

Ok and I assume you must have them all hooked together

What I would do here is try one set first and see if it switches with the proper switch

If it dosen't swap them if that works just cap the 2 that must come from the heater because it comes on with the heater

Customer: replied 5 years ago.
OK I will try in the morning and get back with you. THANKS
Customer: replied 5 years ago.
Glenn I finally got it to work. The last thing i tryed with blind faith was to take the blue wire of the light socket in the broan and tie it to the one incoming white wire and then i tied the white wire of the light socket in the broan to the other incoming white wire. Blue to white and white to white. I do not understand but it worked.
