Sir I was looking for a manual and a service manual for your furnace earlier this morning and like you I can not locate one. But come Monday I could get on from local Distributor and find out where you could get one. I apologize, but if you do need on right away, I do not know where to find it. What is happening that you need the wire diagram? Maybe I can help. servtech50

wires got diconnected between booster or combustion motor, transformer and i think it is called the relay and i need to figure out how to reconnect then

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
Ok I will check into this. I do agree you need a manual/wire diagram. the relay you speak of is it on the intake/ exhaust pipe?
Ask Your Own HVAC Question
Customer reply replied 5 years ago

HVAC Technician: servtech50, HVAC Technician replied 5 years ago

i think it might be a coleman/evcon have you ever heard of that?
HVAC Technician: servtech50, HVAC Technician replied 5 years ago
yes, very common in mobile homes. The problem is coleman does not post any manuals.

Ask Your Own HVAC Question
Customer reply replied 5 years ago

there are no wires hooked up that is part of the problem and on other wiring diagrams ive looked at it shows black and white wire coming of the combustion motor and on this one the wires are blue and black. 2 blue coming off down towards the bottom of the motor and 1 thick black one that splits in 2 up more towards the top of the motor

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
Do you know how old your furnace is?

i looked at these diagrams and dont see booster or combustion motor showing and i need that. someone tried to replace that motor disconnected all the wires and didnt know how to put it back together .there are 2 blue wires coming off the motor and also 1 black thick wire that splits in 2. all wires have been taken off the treansformer and the relay. that is what i need to rewire

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
are you able to do a continuity check on the wires. black to black and blue to blue?
Ask Your Own HVAC Question
Customer reply replied 5 years ago

i dont know what that is

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
You would need an electrical meter to check for continuity, ohms. resistance. I am thinking the blue wires will be an opened circuit and the black wires will be your power to run motor. so when the motor (Combustion blower), turns on and comes up to speed the "end" switch (blue wires) closes and the starts the rest of the sequence. On that relay, there must be some wires still connected. can you trace them and tell me where they are going? servtech50

ther r no wires still connected

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
I know. the wires on the combustion blower are connected to the blower right? jut not connected to the contactor or any thing else. If I knew the resistance I may be able to help here. OH there are no wires connected to relay at all. on relay how many spots are there to connect wires?
Ask Your Own HVAC Question
Customer reply replied 5 years ago

4 hookups

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
The more you can tell me about the wiring and what is wired and to where the wires go would be very helpful in getting your back to being wired. So, is the blower motor still wired? where do the wires go? thermostat wires are they still wired and where does the white wire from thermostat go to on furnace? Gas valve, wired? and where do the wire go to?
Ask Your Own HVAC Question
Customer reply replied 5 years ago

blower motor not hooked up no wires hooked to transformer or relay the rest is still all hooked up wires for plu foe fan switch not hooked up either

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
Wow, someone really took this thing apart! And then walked away? I did not understand the plu? the gas valve is? where do the wires go?
Ask Your Own HVAC Question
Customer reply replied 5 years ago


ya he was supposed to change the combustion motor for us and messed it up totally and my husband told him to hit the road. the plu should have been the plug. im not sure about the gas valve i do know that the wires from the motor r hanging, thereis yellow wires hanging from maybe some igniter box? there is a white wire hanging . It isnt in front of me right now its my daughters house and im not there, i guess its another cold night for her we are in NY and it was really cold last night around 30 degrees

HVAC Technician: servtech50, HVAC Technician replied 5 years ago
I do understand very much. All of us that has tried to help just can not locate a wire diagram for your or your daughters furnace. I was hoping most of it was still wired up because I probably could have figured out the wires for the combustion blower. But if it is a mess like it sounds, it will be next to impossible for me to do that. I can possibly get a diagram on Monday. But until then , I really do not know. You say this is in a mobile home? any idea what so ever how old?

no no title to home, im not sure if there is anything in the breaker box i will look tom. i guess its time to give up for today there is always tom. i think im gonna have a beer

Now that is a fantastic idea. I will continue to look for wire dia. But I think moday will be the best sorry.

I have a request in to the mobile home people that I deal with. They are telling me the model number that you have posted is for an oil furnace. is this true? they are going to fax to me when service manager comes back. but I would like to know more if this is oil or gas. Was it oil and someone did or was trying to convert to gas? servtech50
