    I just replaced my upper door gasket on my Tarm solo40. I couldn't get it to seal. I removed the bolt holding the door spring clip or whatever it's called and noticed it's worn out to about half its thickness.
    This causes the door to have less closing tension.
    The worn area can't be seen from the outside. Its where the door latch rubs against it.
    I was really surprised to see the amount of wear. That would cause the door to loosen up.
    Anyone with the Tarm ought to check it out.

    Thanks Chuck.
    The another hidden item that I look at once a year is the fan. Shut off electric supply and unbolt whole fan assembly. Then you take off the intake grill and squirrel cage fan is accessible. I use a tooth brush to brush off ash from blades.

    For the Tarm and maybe latch wear points on all doors, use a bit of anti-sieze compound to lubricate the contact rub points. Now in my 5thyear and I notice some wear on my door latch. My fix, when needed, will be a touch of spot weld metal and then file it to the proper thickness and contour.

    I was surprised to find that the latch spring had worn by more than 50% and would have eventually completely failed.
    I'm going to check the latch itself. I'll bet that is worn too.
    Compare the top door to the bottom, in my case the bottom door pulls much tighter, it's less worn.
