I have been experiencing intermittent problems with it the last couple of days. The problem is that the heater ignites and but the blower does not always kick on. I understand that there should be a delay, but often times the blower just doesn't kick on. Sometimes the blower kicks on after the flames go out. This problem occurred when I first moved in and if I pushed in on the relay switch, the blower kicked on. Now that trick doesn't work. I had a tech come in and he pulled out the Fan/Limit control and told me Oxygen is getting into the chamber causing the control to knock off. His diagnosis was to replace the heater. [...] Well, I had a second opinion. A guy came out this morning and spent about 30 minutes testing the system (the previous guy took 5 minutes). It turns out that the Pressure Switch is sticking and needs to be replaced. This is causing the system to cycle on and off intermittently. He tapped the switch an recreated the problem for me. He also suggested I wait to have the repairs done during the week so that I wouldn't get charged for an "emergency" repair. It's people like this that give me hope that the world hasn't gone to hell in a hand basket. [...] When we bought this 1963-vintage house ~ 7.5 years ago it had a ~ 20 year old furnace and the original Trane air conditioner. We [link\|http://z.iwethey.org/forums/render/content/show?contentid=36591\|replaced ] the furnace (and A/C because) it was noisy and inefficient and had continuing problems with a circuit board failing (yielding no heat at all). The A/C was undersized for the house, ran all the time and didn't cool the place below ~ 80 F in the summer. Replacement was appropriate for us. Admin [link\|http://z.iwethey.org/forums/render/content/show?contentid=192391\|replaced] his his too, for substantially less than we paid (different brands, areas, etc.). As long as the heat exchanger isn't cracked or there isn't something else major wrong, it can be fixed. The benefits of replacement are it'll be quieter, more efficient, and more reliable. With the cold snap you might have trouble having someone come out in a "non-emergency" visit. But have someone come out. My guess is you'll only be looking at a few hundred to get it fixed. Pumpkin and EGC will thank you. HTH. Luck! Cheers, Scott.

I'm typing wearing biking gloves. I refuse to believe this is an emergency. Barb disagrees, but I will not budge and get someone here on a Sunday. Of course, I will call around, and see if I can have someone tomorrow.

If it does come on, then it is definitely NOT emergency work and you can save yourself $100 easy. If you push something hard enough, it will fall over. _{Fudd's First Law of Opposition} [link\|mailto:bepatient@aol.com\|BePatient]

Post #241,432 by broomberg 1/15/06 12:38:10 PM Reply	OK, thanks Fan + heat on thermostat runs.
Post #241,437 by broomberg 1/15/06 12:44:50 PM Reply	Of course, I might be killing myself I get woozy after it's been running a few minutes. Barb shows no symptoms. The carbon monoxide detecter shows nothing, but hell, it's 10 years old. Not worth chancing it. Turning off - wait for them to look at it tomorrow. Let's review a few days ago. EGC flushes something she should not have. Toilet next to vent directly over furnace get a pretty big hit of water (and other things). Works that night. Stops working the next night. Hmmmmm. Heat exchange corrosion finally push over the edge?

Post #241,474 by drewk 1/15/06 9:01:55 PM Reply	When's the last time you cleaned the inside of the vent? If it was lined with lint, like they usually get to be, then you got grey mud down into the furnace. Can't be good for any sensors that may be inside. === Purveyor of Doc Hope's [link\|http://DocHope.com\|fresh-baked dog biscuits and pet treats]. [link\|http://DocHope.com\|http://DocHope.com]
