The heater repairman says he can’t figure out why the thermostat is’nt working...the heat doesn’t kick in until it’s about 30 degrees in this house!!

So portable heaters abound!!...well just two but they do the job.

WHAT DO YOU MEAN YOU CAN’T FIGURE IT OUT!!

And that’s 2 different ones!

How could a thermostate not be set off at the temp you set?!

It sets off at a lot lower.

And I spend a bunch of time in my man cave in the basement and it’s 20 degrees colder down here!!

I’m not a fixer upper kind of guy.

I’m a room service city boy :)

Thank goodness for portable heaters!

We use these in our camp. It’ll get hot quick with these.

Sounds like the thermostat is wired wrong. Like it is backward. Did it ever work right?

I am not a repair person in the least. Our problem is usually short cycling which is often caused by vents being blocked.

Two thermostats failing simultaneously seems unlikely. Perhaps there is a loose wire at the furnace.

Many thermostats work off what’s called a bimetallic strip. Basically it is a conductive metal strip that bends depending on the temperature, causing a contact to close.

The problem is (outside of a defective thermostat / strip), these strips “bend” and stiffness will change with many flexings. Also, the contacts can be damaged by the arcing which occurs as the contacts make (connect) and break the circuit. In my experience, usually the “shift” is that the contact “break” gradually shifts lower in temperature. For example, I’ve had “quartz” space heaters that after a little use / cycles, had the “overtemp” thermostat shut off at 45 deg. F. New, that didn’t happen even at 80 deg. F.

If the thermostats are new, they are likely defective.

Oh, many modern thermostats use a electronic sensor or a thermistor based sensor. Those can be defective too.

When it gets real cold we’ve started using cardboard barriers to section off rooms and the second floor. The heater used to never turn off and didn’t really heated the house. Now it runs sporadically and we stay toasty warm.

We do use portable heaters in normally unheated upstairs rooms.

Sounds like that heater repairman ought to quit his job and go find some career he might be good at.
