Thanks so much for your efforts in getting with the Lennox Tech. I checked my resistance and have concluded my sensor was bad. I am ordering a new sensor today.

I sure would appreciate what ever you can find out.

Does anyone know how to test an outdoor temperature sensor to determine if its bad? I am trying to avoid buying a new one and finding out that this did not correct my problem. My thermostat is...

I am using shielded wire so I don't think it the wire. So before I purchase a new outdoor air sensor does anyone know how to test the sensor. Is there an ohm reading that it should test out at.

I have a Lennox Series 7000 ComfortSense Thermostat with an Outdoor Sensor (X2658)connected. The thermostat is reading -1F when its 65 degrees out. I checked all the wiring and it appears to be...

Thanks for the clarrification. I even feel better about my investment now.

Lyork,

Just got my electric bill for February. My total gas and electric consumption for the month of February are as follows

LYork,

Got my gas bill yesterday. 7.2 MCF vs 16.2 MCF last year. Thats a 56% savings over last year. Not quite as good as your 69% savings that you got. What do you keep your set point at? ...

Dan, Thanks for the suggestion on the light bulbs. I'll give them a try and see if they work in my fixtures.

Brjones, I agree on running the heat pump as long as I can given our low Kwh cost. I...

Robertshaw 98201 appears to be the same stat that Lennox calls their Signature Stat. When I originally posted my first thread I was concerned about the 4100 Kwh electrical usage in December. My low...

Thank LYork

As you mentioned earlier, you and I have talked a few months back. I believe you mentioned you were in Shawnee. I'm in Olathe. My home is similar size but its a ranch with a dormer....

So from your load calc data I should set my high balance point at 31 and my low balance point at 22. My stat is set to only alow the heat pump to operate at outdoor temps above the high balance...

Thanks Dan. I will compare total usage with LYork come the end of the month.

Couple of questions:

What makes you think I have a defrost problem? I'm assuming thats your best quess given my...

I got the G61MPV-110 furnace. Low fire 75,000 Btuh Input/72,000 Btuh output. High fire 110,000 Btuh Input/99,000 Btuh output.

Main Floor, Loft, and Basement all served by the same system. All...

Designer Dan,

If I understand your math correctly at 4100 Kwh in a month I am providing approx 40,000,000 BTUh. You mentioned this didn't seem like it was overly excessive. Do you still think I...

Lyork, I had my lower balance point set at 10. I was under the impression that I should try to get as much as possible out of my heat pump but maybe I was pushing its limits and running my...

I recently installed a 16 SEER dual source Lennox heat pump (gas backup). I live in Kansas City where the local electric utility gives a rate reduction incentive to go to an electric heat pump (4.3...

Just thought I would let you guys know my results. Your suggestions were exactly what was causing the noise. The installers fastened the refrigerant lines to the joists in my basement with metal...

I'll try both ideas.

RoBoTeq, I have to ask, what is a ignot? Are these something I can purchase at the local hardware?

t527ed, Are these metal sleeves you speak of supposed to be removed...

The refrigerant lines are approximately 30 feet long. The systems is a Lennox G61MPV Variable Speed Gas Furnace with a Lennox HPXA19 Heat Pump. Both are marketed as being extremely quiet. I...

I recently had a heat pump installed. The charge was checked and was a bit high so they removed a portion of the freon. The lines were noisy and have quieted down somewhat but unfortunately the...

I figured out why my refrigerant lines were making so much noise. Temperatures in Kansas City finally reached the high twenties and my heat pump went out on high head pressure. The contractor put...

Great to hear Mopar Guy. I do allot of design work with Lennox Technical Support so I asked them to send me the wiring diagram for my system using the Signature Stat and it showed this jumper in a...
