    For some time this geriatric freezer has run constantly on superfreeze (achieving -32C) as it had developed a habit of not restarting after cutting out when it reached control temperature.
    Then we had a power cut.
    Restart lasted around three minutes then blue flash and big hole in PTC starter.
    This was replaced and the freezer ran for around 24 hours then stopped.

    Now, when switched on, the compressor runs for around 4-5 seconds then stops. This repeats after PTC cooldown.

    All suggestions welcome

    Thanks

    Maybe a faulty replacement start device,maybe start windings damaged when power came back on.
    It’s not the ptc cooling down it’s an internal protection device in the windings of the compressor that will cut out on overload or overheat,could be a winding gone but under the circumstances would plump for the new ptc failing (they are prone to absorbing damp if stored uncovered).

    Thanks spimps

    Tried another start device. No go. Same as before with restart after 25 – 30 seconds.

    If the start windings were damaged on power up after the power cut, would it have started and run for 24 hours after the new starting device was fitted?

    Any idea what resistance I should be getting across the pins?

    thanks for your input

    Depends on the temp,if you measure between all pins you will have three readings.
    The top pin is common to both windings, so, common to one and common to the other should add up to the reading between the winding pins.
    ie the two smaller readings should add up to the larger reading.
    You could if these are correct have a mechanical fault so the rotor won’t turn or is jammed which would give the same symptom.

    Ok – the bad news.
    Measured resistances, and sadly, they don’t add up.
    Looking towards the pins (bottom common)
    bottom to top left – 7.3 ohms
    bottom to top right – 13.1 ohms
    top left to top right – 10.2 ohms

    Readings taken cold (but not freezing unfortunately!)

    So I presume it’s bye bye TC115. 🙁

    Dug out the manual this morning and found the receipt with it.

    Bought on 8 August 1978 for £129.75.

    That was an expensive freezer then, but after 31 years and 3 months, I think you’d agree it was pretty good value.

    Mine, TF113 has just reached 34 years,quality product.I did put a new compressor in mine a few years ago because the cabinet will out last me 😯
    I worked for them during that period that was a Sweedish built product,must have had a Volvo designer in on it.

    I take it you’d agree my compressor drive’s had it.

    Where did you get a replacement from? Costly?

    You’re right about the cabinet – it’s built to last.

    Mine’s Danish.
