Kndaplgrl Mar 22, 2009, 10:40 AM I have a Trane furnace that is 8 years old.
The thermostat in the house was replaced with one that could be programed. Even when programed the furnace will run, shuts off and comes right back on again. This will go on for quite awhile.
In looking at the furnace I notice there is a timer on the left side which is not set at the correct time of the day. I didn't want touch anything until I checked with someone first. Shouldn't that be set to match the correct time of the day?
Thank you.
wmproop Mar 22, 2009, 02:12 PM they say its hard to stop a trane,,they don`t tell you how hard it is to start a trane
did this problem just start when the new tstat was installed?
if so I would go back and look hard at the installation instructions,,something just not right
Kndaplgrl Mar 22, 2009, 03:02 PM No it has been doing it off and on for a long time.
However I just noticed this timer box this morning which is not set to the correct time.
KC13 Mar 22, 2009, 03:25 PM Do you have an Electro-Wash air cleaner? The timer may be used for scheduling the wash-down cycles.

KC13 Mar 22, 2009, 03:53 PM Keep an eye on the timer - is it running/advancing? Can you determine what, if anything, it controls?
Kndaplgrl Mar 22, 2009, 03:59 PM Yes it is advancing but the time is not correct.
I have no idea what it controls.
mygirlsdad77 Mar 22, 2009, 04:04 PM can you take a picture of this timer and post it here? it may help. Although i doubt the timer is causing your furnace problems.

KC13 Mar 22, 2009, 09:03 PM It looks like a Tekmar setback timer. I've seen them used on boiler systems in apartment buildings, but never on a residential forced-air system. If in doubt, remove the dial cover and adjust the clock to the correct time (by turning backward, if memory serves me). The tabs on the dial can be set to "ON" or "OFF". Setting them all to the "ON" position will render it ineffective.
Kndaplgrl Mar 23, 2009, 10:17 AM Ok I will try it then.
So I should put on off then to make it effective?
mygirlsdad77 Mar 23, 2009, 03:08 PM personally, i would put it on, which will bypass the timer. I dont see any need for this timer on a forced air system. If you do turn it to on, it will eliminate the timer as your problem. Then we can take the next step to find the problem.
