Get some heat for 10 - 15 minutes and then no heat. I replaced the fuse and it worked good for a couple of weeks and now it is happening again. The new fuse was not exactly the same as the old but that is what Sears called for a replacement.

Do all again

I think there is a short in the system, possibly happened while replacing the main brain.

try to replace your thermostat and conduct observation with your furnace if happen again after replacement of thermostat furnace also damage.

fuse look in handbook or fuse cover and replace

After it is stored for the 2 weeks, do you turn water on to it, then bleed out any air through the taps before lighting it? If not try that and see what happens and let me know if any different.

I had this happen on my '03. I had to bring it to the dealer and they cleared a code a it worked again. They said it wasn't a fuse or anything, but that the module had to be flashed. It has been working for the last week. When it happened to me both the heated seat light and the ac seat light was not working on the passenger side.

your cycling thermostat needs changed too. the thermal fuse is your last safety measure that goes, which means your cycling thermostat is not shutting down the heat element once it detects the right temp hot air in the blower housing so it let the heat element glow until either the high-limit sensor shuts the heat down or the thermal fuse blows. Change the cycling thermostat and good luck

are you saying the unit go's dead if thats the case there is internal protection shutting it down and some troubleshooting would be required to figure out what is causing it.

Have you ever change the fuel filter? if not then try this

Hi,

It is often difficult to diagnose/repair an intermittent problem. It could very well be any of the circuitry and components inside: video interface, CCF Lamp, inverter, power supply. All of which would require that you open the casing and poke around inside and that you be familiar with electronic components & circuitries, soldering and use of a continuity/volt meter.

Doing so would void your warranty (being just a couple of months). Perhaps your best bet would be to seek repair/replacement of the monitor from your dealer/supplier and describe fully the nature and frequency of the incidence. It may be that when they test it will check good.

Should you choose to open it up yourself, post back.

Good luck and kind regards.
