Intermatic timer

Post by Nyc10036 »

I have an Intermatic E1500 in the downstairs bathroom.
https://www.amazon.com/Intermatic-EI500 ... B003A3WUU2

It has gone completely dark.
Not sure when it happened as we don't use it.
One of the Amazon reviews mentions a backup battery which is apparently not replaceable.

Is the reason it is completely non-functional because a wire came loose
or does the backup battery having anything to do with it?

Based on your link, batteries are required and probably need to be replaced.

included Components EI500WC
Batteries Included? Yes
Batteries Required? Yes

I have not had much success with Intermatic timers as they seem to fail before they should. Just replace it with a new timer.

Thanks.

It looks like the Honeywell one would be a better choice.

Likely the battery but, did you try the reset button to bring it to factory settings?

I shouldn't have to ask this, but...

Did you check the breaker?

That timer replaces a switch.

Those that are telling you to replace a battery don't understand the timer. It has a battery BACKUP. Backup means that if the power fails, the battery kicks in. Therefore, if the battery is dead, but power is on, the timer works fine. This battery is rechargeable and non-replaceable, easily found on the Intermatic site - https://www.intermatic.com/en/in-wall-c ... rs/ei500wc

Wires don't just "come loose".

$10 bucks the breaker blew.

The Intermatic is the third switch in a set of three that are side by side.

The other two switches turn on the light over the vanity and the light in the shower stall.
I expected some "life" from the Intermatic, but it is completely unresponsive.
No display whatsoever.
The other two regular switches work.

So the timer powers what?
3 switched in a box could have different sources of power and different breakers (IANAE)

But there isn't a separate breaker for just that switch.
The circuit breakers in fuse box are all accounted for.
I know that the Intermatic worked once, but I don't use it.
It turns on/off heat lamp in the ceiling (I think).

I have one like this. It has been used daily for 15 years. It still works like new. https://www.intermatic.com/en/in-wall-c ... mers/fd2hw

I wonder if the ones they sell now are as good as the ones from 15 years ago.
That's the problem with things these days.

That makes no sense. The timer you linked to is a 7 day timer. It would be used for example to turn on your foyer lights every day at sunset and keep them on till midnight.

A bathroom heatlamp timer would be used to turn in a heatlamp and then say 10 or 15 minutes later turn it off. Most of those look like this Image or this Image

Sounds like you need an electrician to figure out what you have and why it is not working.

So you found a breaker for the heatlamp?

One other thing to check for is if there is a GFC outlet on that circuit that has been tripped. That could be anywhere in the circuit like in a different bathroom.

If you get nothing on the display there's a good chance the unit had an internal failure of some kind.

You may want to confirm the problem is with the switch by replacing the heat lamp bulb with a known good bulb (doesn't have to be a heat lamp bulb but it has to be able to fit the socket) and see if the on/off feature of the switch works. A bulb can fail in the base so they don't always fail with power on.

If you don't use the timer features it might be better to replace the timer with a regular switch.

As another poster noted it seems unusual to use the linked switch as a timer for a heat lamp, unless someone wanted to warm up the bathroom, perhaps in the morning before getting up.

Guys this isn't rocket science. The timer died. Doesn't matter what's connected to it or if whatever is connected to it even works. The timer is dead, period.

Replace the timer. End of story. It also doesn't matter that it's "strange" that a 7 day timer is there. Any previous homeowner could have installed it because they wanted it for whatever reason, thought it would be useful, was the only one available at the time in their local store, was the only timer compatible with the electric system or what it was going to control, etc.. who knows why and doesn't matter. It was there, it's dead, now it can be changed to a regular timer.

Turn off your breaker, verify that the switch is connected to that breaker and has no power, and install new timer one wire at a time in the same configuration as the old timer.

However, this is only general advice for a DIYer with some general knowledge of electricity. You think it controls a heat lamp but aren't sure doesn't inspire confidence in suggesting to DIY anything.

Also since it might be used to control a HEAT lamp, do not use a regular switch. If you forget to turn off the HEAT lamp while you're gone for 8,9,10,12 hours............ use a timer switch.

Agreed, I had an intermatic timer switch for our front lights that almost never worked properly. Would be ok for a week or two, then would turn lights on/off on a totally random schedule--check the programmed schedule and it still claimed to be correct (and of course the time was right).

Eventually I smashed it with a hammer and replaced it with a smart switch and set routines in the app. It works perfectly 100% of the time.

Thanks all for the insights.

Since I will be hiring an electrician to replace the three outdoor lights when I sell my house I will have him replace this broken timer as well.

Ours has been running the foyer lights for 16 years. Two twist timers in bathrooms, also Intermatic, 16 years. Outdoor landscape light transformers too...

Took me a while and some effort to finally find the tripped GFC outlet in my new to me house.

I've never had a problem with their twist timers, or their outdoor (120V or low-voltage) rotary units. But their electronic programmable ones are absolute garbage in my experience. This is not the first thread on here where people other than myself have had problems specifically with their digital timers.
