furnace info needed

Unread postby gezundheit on Sun Sep 15, 2013 8:47 pm

i have a 1973 220.i tried the furnace the other day.the pilot lights but main flame does not.i'd love to check out all the switches and interlocks but they all are in the back area of furnace and what do i do to get to them? the furnace is located under
the kitchen sink area.do i need to pull that area apart? or is there some other way to get to it? i have a 1/2 tank of propane.i mention this because someone said that a low tank could cause hard ignition problems.my stove lights up with no problem.
thank's all.regards,gezundheit.

So you are saying the pilot lights and stays lit after you release the button ?
The firebox will not flame up until heat is called for. You have to turn up the thermostat. If turning up the thermostat higher than inside temp does nothing then your thermostat it bad. you can jump the wires on the back to confirm. If when you turn the Tstat up the blower fan comes on and pilot is lit but you are getting no flame then you have another issue. Report back.
Also anyone who reads this that is not familiar with propane, please read.

If you need the manual for your furnace let me know. I should have one.

i have another issue.all the things you mention about the initial furnace startup work ok.i think the problem is one of the limit switches.the manual notes 3 of them.a fan,hi limit and a micro switch.in order to test these switches,i need to lay hands
to the back of the furnace,which in my case is beneath the kitchen area.so my question still applies,whats the easiest way to get er out?

Assuming it's like mine You have to unscrew the outer vent on the outside of the RV(the smaller one in the middle, it screws directly into the vent tube flange). Disconnect the gas line, and I think there are two screws under the front cover that hold it from sliding out.

might be a little late for this response, but mine didn't work at first either, the pilot was on, but not enough. I held the reset button longer, made the flame bigger, and I'm assuming its like most pilot light setups, completed the circuit by heating the thermocouple.
