We just had a new larger manufactured home placed on a 10ft poured wall basement this summer. The home is less than 5 months old, as is the Furance.

I live in Michigan, the nights can get 10 degrees or below in the winter nights, and sometimes in the days as well, usually 20 - 30 during the days.

Our furnace is made by Nordyne M2R Series, downflow model.

This thing keeps turning on and off like crazy, for example I have spent the entire night listening to it turn on anywhere from 3-10 minutes, shut down from 3-7.5 minutes, and then back on. More often than not it runs for about 5 mins, off for 3 and back on. It has been doing this for the whole cold season so far, and driving the whole family crazy.

It is loud as can be, the TV goes up, and my husband out the bedroom door screaming at our teenager to turn it down, but really no one can hear the TV when that thing is on.

PLEASE!!! Any help would be great, also the rooms are very uneven in temp, 1 thermostat for this whole big house.

Thank you so much for your time!!

If you have a mechanical t'stat, try raising the heat anticipator setting.

Hi Beth:

That would drive me nutso. Things to check:

1. like fj said, mechnical t-stat- check the anticipator setting against the amperage draw listed on the gas valve. Gas valves are usually like .3 to .5 amp and you match the number on the anticipator with that.

2. Programmable t-stat- take it off the wall and look for a cycles per hour setting [cph]. They often come set from the factory for 6 cycles per hour which is too much.

3. Check to see if the hot air supply is blowing on the thermostat causing it to cycle so much.

4 Uneven temps- you may have to adjust the airflow out of the registers

5. Buy the teenager some headphones that plug into the TV.

Does your place sit up on a 10 foot high foundation? Wow- you could finish that space off for storage and a play/TV room for the kids.

Thank you for your fast replys!! That is very kind!!

I relize that I didn't say it was a propaine furnace.

I do not see the amp draw on the gas valve, all there is, is the valve!! My T-Stat is set at .4

I am new at all of this, I am learning everything as we speak. If I sound dumb, please forgive me!! I have read threw the manual and everything online I can find and it's still greek to me!

My husband is of no help, he has only rented his whole life (and his parents as well) so he don't have the 1st clue to what to do, and he is one of thoes guys that just don't care. I think we are using to much propaine with it running all the time and I happen to care about the cost as well as it working correctly!!

I also went and got a new filter, as I just found out last night it is susposed to be replaced MONTHLY!! :D

The head phones are a great idea, however I do the same thing as the boy, turn it up over the noise. (lol!)

Yes, we are on a 10ft high fondation, 1764 sq ft of cement that holds a bunch of old furniture and the husbands tools, (not that he actually uses them to help with this house!) We do plan on setting up part of the basement for the kids area, but my cash flow is at a min. after building this house!! ;)


Again, I thank you so much for the fast reply, what can I do to find the valve setting?

Try raising the heat anticipator to .8 and see what happens. Propane, huh...Was the gas valve converted over to use with propane? It should be marked somewhere on the unit. If not, it's time to get yourself an HVAC company. Propane works at a much higher pressure than natural gas and the Nordyne company ships all furnaces ready for natural gas. If it was not converted your putting yourself and your family in a very explosive situation..Better to have it checked than lose your home or family...

You said you have been in this house for LESS than one year, your warranty for the house is still in effect, tell the builder to fix it. Put HIS feet to the fire. The builder warrantys the house for one year. Did this just start , or has this been happening all along?
:cool:

The people that I custom ordered this home from are a big joke!!

Sadly, there are a number of problems with these people, when I call them for any questions they tell me to call the number on the appliance. I have already had the water heater replaced.

They were susposed to be my general contractors, I even paid them an extra $2,000.00 to be my general contractor because I knew nothing about any home building, but all they set up was putting the house on the basement, (I had to sub-contract the basement also) which was a hassle in itself. I had to personally sub-contract everyone else with this house, and things were never finished in the home to begin with, I had to finish things myself. (Trim, Painting, Cracks from the move, door stopers, decks, basement steps ect ect ect...)

The valves were switched to propaine by the propaine company when they placed the tank, so that I know we are good on.

I have thought about getting a lawyer to help me with getting things straight but I took every penny I had to get this house going, I put in $100G and loaned for $35G, and now fear the costs of a lawyer would go over the costs to get things right.

I had the house built in July and the furnace has acted this way since we first turned the heat on in October. I thought it was just because this is a manufactured home that it is like that???

I will try putting it up to .8 and see what happens... Thanks again!!

An old saying, only the wheels that squeak get the oil.
Called the attourney generals office and get an appointment to see him, bring all documentation and notes who you spoke to and what was said on paper. Remember he works for you, call the president /CEO of the maker of the house, modualr homes are usually better built than stick builts. When they tell you to call the manufacturer, say no YOU call him, I bought this from you not him! Call the chamber of commerce and the better business bureau as well, The building inspector needs to pony up as to why he gave this an occupancy permit with so many problems.....get on the phone and be a pain...telephone is your only cost, if you have a camera take pictures...
