Bad thermostat? No heat upstairs, heat works downstairs

I have a Honeywell mercury thermostat upstairs that quit working yesterday. I can't get it to kick the heater on. I'm not sure of the exact switch/stat model number b/c there are any identifying marks/numbers that I can see on the stat but on the inside of the cover it says "LR1620 Class 2 30V Max". Not sure if that helps.

Downstairs we have a digital stat and it works fine and the heater is working and blowing hot air just fine. Upstairs I get nothing: no air, no heat. Any ideas on my best course of action?

I see some recommendations to switch this mercury style to digital. What cost should I expect to replace this switch with the orig and what would digi run me? I'll hit Lowe's/HD soon and get some info from them too.

Is it likely something I can repair or adjust on the stat or does it sound like it's failed and needs to be replaced? It's about 6-7 years old.

Thanks,
Chris

Gas, electric igniter

it's gas heat with an electric igniter. i replaced the stat, no luck. cycled the breaker, no luck. cycled the gas valve switch on the heater, no luck. cycled power via the switch at the unit, no luck. the fan will come on though after power is turned on but the gas will not flow and thus not ignite. i have coming to look at it... i hear the igniter can go bad, so maybe that's it. i don't know make/model on it but if this guy doesn't fix it then i'll get that info.

Heat pump thermostat wiring

R

robteed on Dec 14, 2004

We installed a new Geothermo heatpump in our house. I have it working but it needed a Electric heat strip added because of frost buildup on the unit. I guess the heat strip is suppose to take some of the heating load off the HP to give it time to defrost the pex tubing lines. The guy that sold us the heat pump isnt much help, it was sold as a DIY kit. The pump has these connections :C:S:L:G:O:Y:R The Electric heat strip has these connections :W1:G:W2:C:G1:R:W3 The wiring diagram shows W1:W2 are jumpered together, they can be disconnected. The Thermostat is ####LUX HP2110 2stage heat/1 stage cold programable from Menards. The connections for it are :E:G:Y:R:O:W2:B I have an 8 wire thermostat wire running from the themostat drectly to the Heat pump. I have another 8 wire running from the heat pump to the Electric heat strip. How should all these wires be hooked up? Right now im just running the four GOYR HP to GOYR Thermostat. Nothing to the Electric strip. I do have the 240 voltage hooked correctly. The heat pump keeps the house at 69degrees right now. But the frost on the lines worries me. We also have three gas fireplaces and one wood fireplace that help to heat when it gets chilly. Thanks for any help.

When my heater runs, my house stinks??

I just built this house 5 years ago, and every year when we use the heater it stinks in here. It's not the smell of something burning like the first time that you turn it on each year...this is a very weird smell, it makes my whole house stink. We called the AC man that installed the unit the first winter we used it, and he told us that it was a smell coming from the pee-trap in the attic, and it was his workers that made the pee trap in the attic. So my husband got up there and changed it and put a real pee trap up there, they had just pieced together pieces of pipe. But this didnt stop the smell coming in. It only smells when the heat is blowing through the vents. So I have another AC guy coming out this week to see if he can figure out what it is. He had said before when I talked to him that some brand new units just smell the rot when they are turned on. Do any of you know what this could be? I have central air and heat. Thanks...and I hope someone can help me out!! Kim
