220v timer?

[SpatiallyAware]

I have a friend who has a dryer with a bad timer. They are turning the dryer on and have to remember to turn it off..... A disaster waiting to happen.

A new timer is $100+shipping, more than the value of the dryer.

I've searched for 220v dial type timers, similar to a kitchen timer, with no luck... Turn to 60 min and it shuts off automatically. Any tips on finding one?

How much current are we talking about? May be too much for the little timers you are thinking of.

The problem with those is that they aren't countdown timers....

I'm thinking something similar to a pool light timer, or house fan timer...

 

[LTC8K6]

Just use the "off" markers and set one to an hour from "now" when you use the dryer. Same as a countdown timer.

It sounds like you want a "spring wound" timer like one of these: http://www.grainger.com/Grainger/sp...71&Ns=List+Price|0&itemsPerPage=60&sst=subset

But I don't think you will find a plug-in version of those, so be prepared to do a little wiring.

Alternatively, if you or your friend are willing to do a little work, get a free dryer off of craigslist and steal the timer out of it. I see tons of people dumping old dryers that no longer heat up, but probably still have perfectly good timers.

Perfect! That's exactly what I'm looking for. I'm fine with wiring it, as it seems like it would be useful for other things once the dryer gives up.

So buy a new dryer...

Not appropriate, given the situation. I'm trying to help someone out with parts etc not buy a dryer.

 

[LTC8K6]

I was thinking you wanted a plug in type. The wired ones are actually pretty easy to find.

I use them all the time, and I would send you one except the ones I use are 12 hour versions, which is too long for a dryer shutoff.

I use these for soak timers.

Better check the current rating, too.

10A is probably too small.

Thanks for the advice, and the offer of sending one. I have a grainger nearby, I'll post up what I end up doing.

Except that most of those are 220v @10Amps, and dryers are typically 220v @30 amps.

Post the make and model number of the dryer while you're at it. Maybe our collective google-fu can return a cheaper replacement part...

But then you have the dryer coming on the next time the tripper reaches that point on the dial (the next day!).

Those wind down timers won't have sufficiently rated contacts for a 230V residential dryer. That's 5.5kW + (typ 1/3hp induction motor) which is usually wired with 10AWG and protected with a 30A double pole breaker.

You could use a 30A double pole contactor with a 120V coil and THEN use the wind down timer to supply the 120VAC to the coil. Actually with this arrangement anything that will switch 120V will work such as X10 modules, etc. (this is a good way to put an electric water heater on a timer, for example)

No, you remove/don't use the "on" trippers.

That could work if using one like this:

Like a water heater, a dryer is predominately resistive load. The AC timer is not "beefy" enough for an electric dryer.

If handy just use something like this:

To provide coil voltage (control) to this:

Yes, someone already said that... :whiste:
