I am not. Just stating the fact. You call someone an idiot to counter his opinion and/or discredit him. I am countering your flattery statement here. In this context, you deserve to be an idiot.
Er, yes. It was only a randomly selected item for the purpose of the discussion about power ratings. There are indeed much cheaper relays available that would, on the face of it, be up to the task.
Sylvia.
I'd never use something that isn't expressly rated for the voltages and currents I intend to use. There's nothing about a relay rated at 12VDC that would guarantee that the insulation is up to use for mains voltages.
Sylvia.
It's not just a few watts. The rating plate says that in defrost mode the fridge draws 450 watts. That may be the initial power when the element is cold, but even when it's hot, it's clearly going to be drawing significant power.

A furnace relay should work: 8A @110V, 24V coil for around $10. I use a 5V relay to activate the 24V coil, but you can also use a MOSFET.

**Very likely a misunderstanding.You called my post irrevant
**The implication was clear.1) That Australia was a Socialist nation.
2) That the US was not. 3) That the US was becoming a Socialist nation.I will state again:
ALL Western Democratic nations operate as Socialist states. Every single one. Including the US. Always has done. Ever since the US Federal, State and local governments began collecting taxation, the US has been operating as a Socialist nation.
What JT IMAGINES is that Australia is more socialist than Australia. That may be true for some parts of the society and less so for other parts. In the case of the medical system, for instance, Australia enjoys a largely socialised medical system. Australians are very happy with that system. The US lacks a cohesive socialised medical system. As a consequence, some 50-odd million Americans have extremely poor access to good medical services. Additionally, some 60% of personal bankruptcies in the US are due to medical bills. Here in Australia, no one loses their home so they can stay alive.
And to get the issue back on topic, the US regulatory authorities have considerable influence of what can and can not be connected to US mains power. In the US, however, due to the low mains Voltage, there is far less risk to consumers than there is here in Australia.

Why is this a bad thing? The governement won't stop you (or me) from experimenting on the main, but would stop us from selling unsafe products to unsuspecting customers. Otherwise, i would have sold you a furnace with auto relays. Don't blame me for burning down the house.
**I don't consider regulation necessarily a bad thing. LACK of regulation is, in general, far worse.

Not sure about getting a 555 to run at 1 cycle per six hours.
A PIC would no doubt do the job easily, but then I'd have to invest in hardware to program it.

The symptom of failure is that the motor is making a noise. It's a familiar grating noise that I've heard from other aging clock motors. I presume it's the rotor rubbing against the stator, given that the rest of the mechanism consists of nylon gear wheels, though someone may want to advise otherwise.
Sylvia.
I'm laughing at the turn this thread took. If she installs her own circuit, she is modifying the thing with a non-oem part, regardless of what parts she uses in her circuit. Thus any concerns about fire/liability/insurance/local regulations apply. Doesn't matter if it's flame retardant, 240VAC rated, gold plated, whatever, the exposure is still there.
She has already indicated she would not use an automotive relay, so it's moot as far as her project is concerned. But I wonder, has anyone else here actually tested one of those relays at 240VAC? I have, and it worked fine, but I did not test to destruction, nor for dielectric strength or flammability.

yeah, over voltage, or excessive dV/dt, will turn them on, but couldn't subsequent over-current cause them to fail closed?

CD4060, CMOS logic, an R-C astable and a 14-stage divider chain in one DIP package, but not strong enough to drive a relay directly like an LM555 would be.

less risk of fatal electric shock, more risk of fire from overheating conductors.

You wouldn't say that if you ever see an outlet explode and blow a hole in the wall, when lightning hit the power line a mile away. I have. The noise was deafening, and scared the hell out of my grandparents & parents. It took out all the power on my grandparents farm, as well.

We have underground utilities here. Some years ago a lightning strike at a substation 4 miles away blew out numerous appliances, several PC's, a TV set, and every light dimmer in the house. ...Jim Thompson
