Something is wrong with the thermostat.  replace it first, that would be the cheapest alternative

Fraser Johnston Furnace - Not heating


Check the furnace filter to make sure its not dirty . Dity airvfilters can cause the furnace to overheat and shut off on a high temperature limit switch when the switchs cools down it resets but the furnace has to be shut off to reset the control board. Hope this helps.

I turned my thermostat down this morning to 68 degrees. I came back about 2 hours later to increase the temp to 70 degrees but when I push the ^ arrow instead of showing the increase to 70 it just flashes...


Since it's within 2 degrees of your setting it could be one of two things. Most furnaces run longer (pass your setting) to maintain the setting you made. Which really not a problem. However, your thermostat may need calibrating. To test this theory, place a regular wall thermometer next to your furnace's thermostat and see if the two temps match when the furnace cuts on and then when it cuts off.
If the temps are both the same, the furnace thermostat is fine.

If you're turning it down to 68, because no one will be at home during the day, just set it 2 degrees cooler than 68 degrees. You will then wind up with 68 degrees.

Definitely a thermostat.It has 2 sections.One is a temperature reference section(what temp you want).The other is the temp reading section.If either one is bad,it will do just like you said.Sounds like the reference section is probably bad because it comes on for a couple minutes then shuts down.Since it was fine earlier in the day,I doubt there is anything wrong with the furnace because as you can see,it is temperature related.A furnace problem would be more of no operation at all,even if just dirty or whatever.The thermostat also would be a more common 'fail component' than the board.A suggestion also,both for a car and a house.During the summer,run the heat for 2-3 minutes,just to cycle it occasionally.In winter,run the A/C for 2-3 minutes.Do both perhaps once or twice a month.It helps keep the components,somewhat fresh I guess you would say,because cycling it occasionally helps to keep it going good.Also,if you encounter a problem,you may be able to get it fixed before you really need it.In the meantime,feel free to come on down to FL until it's fixed,we have room,lol.Although it's chilly now,the weekend will be 70's.(sorry)Good luck,Greg

Furnace doesn't ignite all the time.


That is usually the flame is dirty and not sensing the flame.
You can clean this by first turning off all the power to the furnace.
Take the door off to burner area and locating the flame sensor it looks like metal rod and it is in the flame of one of the burners.
Once you locate it, take a piece of extra fine steel wool and clean it.
Put door back on and turn power on and furnace should run.

Check the board for a set of dip switches. Check against the old board for switch positioning. These control fan on/off times. Ensure you turn power off before changing switch positions. If no dip switches,??

I have a gmpn-80 janitrol 90% eff gas furnace,it is only 15 months old,my condisation tray is melting and cracked do to heat in which case leaks water all over....why would this be happening?


Most likely the cause is that the furnace is firing too hot. When a furnace is installed and set up, the manifold gas pressure and fan speed has to be set by the technician so that the temperature rise through the furnace is a maximum of 50 deg F (i.e. if air enters the furnace at 68 deg F it come out no hotter than 118). The target temperature rise on any gas furnace is anywhere between 30 and 50 deg F. If the furnace runs too hot, either the manifold gas pressure must be turned down or the fan speed must be turned up to keep in this range.
