OLD wall timer Model E1020 ticks really loud

I have OLD wall timer Model E1020 tied in with spare bathroom fan for on/off. Seems to have started ticking really loud.
How can I make it tick quiet
or stop ticking and turn fan on manually when I want it? Was installed when house built for building code.

You probably can't get the existing mechanical timer to operate any quietier, since it's old and likely starting to wear out. You can either swap the timer out for a new automatic digital timer, or install a standard single pole switch in its' place.

I believe the code you refer to regarding the fan having to be wired onto a timer switch was a local requirement from many years ago.

Some local jurisdictions have impossed more stringent requirements, but frankly, having an exhaust fan is normally a good idea. If the fan is vented into the attic space, it can cause some serious problems in cold weather with condesation of the warm, moist exhaust air.

Building Code requires that bath fans be piped/vented to the outside of the house and not into the attic space.

There are newer preset timer switches that will turn on the exhaust fan for a fixed amount of time, based on which button you push. These are great as they will run the fan long enough to remove condensation from showers, etc.

If you're going to replace the timer, disconnect or turn off the breaker or power to the switch. Then simply install a new timer or switch by connecting the black supply wire to the bottom of the single pole switch, or to one of the black leads of the timer. Then connect the black wire going to the fan to the top screw on the single pole switch, or the other lead on the new timer. The white (neutral) wires should already be connected with a wire nut inside the box. Connect the ground wire to the ground wire in the box and if the switch box is metal, attach the ground wire to the box with a green grounding screw too.

You can now operate the fan with either a manual on/off switch or the new digital timer, whichever you chose to install.

How to disable Intermatic Timer e1020


Pull out the center dial. Or just remove trippers after pulling out center dial.
That action will stop ticking sound but wire will be exposed, so cover with tape.

What is the intermatic e 1020 used for just moved into a house andits in the bathroom and makes a lot of noise.


The E1020 timer is reliable heavy-duty 24-hour on-off analog timer with replaceable trippers and manual override, rated 12 amps.
This timer replaces ordinary single-pole on-off switch.
Timer has extra white wire that connects to white neutral wires inside box to run timer mechanism, while mechanical single-pole switch does not need this wire.
I don't know what it is doing... maybe running the vent fan periodically, or turning on attic vent fan?

For same timer, with less noise, install E1100-1200 aka the KM series in-wall analog timer. Or install digital in-wall timer, or replace timer with on-off switch.

My panasonic fan has been working fine for the last 4 years. now, it seems to have trouble starting up... when i flip the switch on, it seems to start and re-start itself, turning itself on for 2 - 3...


Sounds like it could be a loose or intermittent wire either in the fan itself or in the wall switch. I would start with the wall switch to see if the main power line into the switch for both the fan and light is loose. Turn the circuit breaker off for that circuit, remove the wall plate to the switch and pull the switch out of the box to examine the wires. It could also be a loose wire in the switch box that would be part of a wire splice. Tighten the wire nuts. If that does not fix the problem, a look inside the power box of the fan might be necessary to examine the wire connections there.
