Heated Floor Thermostat Gfci Keeps Tripping

The test is successful if the red led on the right of the thermostat flashes once The thermostat is for flush mounts in a wall socket.

I checked the resistance in the heating cable:

Heated floor thermostat gfci keeps tripping. Two or three months later (and almost simultaneously), two other thermostats began to trip. The control may have been bypassed. If they are bonded together, the gfci will always trip.

If the gfci doesn't sense the same current on each wire than your leaking to ground somewhere. Here's a picture of the thermostat (complete with red light) If you tried to reset gfci and keeps tripping, there maybe a fault in your floor heater.

The gfci trips if their is an imbalance between the two measurements. Having both the thermostat gfi and bathroom gfi connected could be an issue. Click here to fill out a.

The imbalance when it trips is very small like 5 milliamps. Something you can check is to pull off the existing gfi face plate and remove the exiting gfi outlet (power off, and ppe) to. The system does not produce enough heat or takes too long to heat up.

Installation and use must be according to the national and local regulations. A resistance test across live and neutral should be completed and the reading should be checked against the values in the installation manua l for your. Fifteen years ago, a contractor installed easy floor heating system under tiles in our lower level.

Since this has been working for two years, that is probably not the case but it is odd that another thermostat came up with the same issue. The appliances plugged into the gfci, such as fridges and converters, can cause it to trip. Mat keeps heating floor after it should stop heating.

Set the thermostat to 'heat' the floor; Other potential causes include faulty wiring, loose connections, and a faulty gfci. Factory default floor limit setting is 99°f, but may need to be set lower for laminate floor coverings and other similar floor covering materials.

If the thermostat does not trip the gfci reattach the mat/cable (load) wires to thermostat terminals 1 & 4 and set the thermostat to a ‘heat’. If it did not come on by itself, press & hold the on/off button located on the bottom right side of the thermostat faceplate) for 4 seconds. It is important that the gfci is tested monthly.

Try turning the breaker off for a minute then back on, that usually fixes these gfi trip issues. An electrician will need to test the system and ensure that it is not an issue with the rcd or electrical installation. If the thermostat trips the gfci with no load attached, then the thermostat's gfci will need to be.

If the thermostat trips the gfci only when a load is attached then the issue is in the floor and a site visit from a repair technician is required. Reset the breaker and wait a few minutes to see if it will trip. There are four gfci programmable thermostats wired to 240v service.

208 v) 50/60 hz power supplies. The ground fault protection will guard against electrical hazards in case the electrical floor system is damaged. Use a thermostat with the gfci built into it.

If it does, other faults may be responsible, but if it does not, suspect circuit overload. About five months ago, one of the thermostats began to trip flashing a gfi fault. Normally we’d be a little concerned that the gfi is tripping because something may be damaged under the floor.

If you get near 0 ohms, you have a short. If thermostat is setup properly and activates the heating system as it’s supposed to, underlying issue may often be with the flooring itself. I installed a new fg thermostat and the thermostat gfci has been intermittently tripping the since it was installed.

Turn off the breaker, pull the thermostat, measure resistance between hot and ground and neutral and ground. Try switching the thermostat off and then back on again. Initially, resetting the unit would work for awhile, but later it would not set at all.

To see if it is circuit overload that is causing your gfci tripping, unplug the appliances plugged into the outlet. When i turn the power on, the gfi built into the thermostat trips right away. Turn on the circuit breaker controlling the floor heating circuit.

The system operates at 120 volts, but the thermostat is capable of using either 120 or 240 volts. The gfci will trip because loose connections, worn insulation, moisture, contact with human skin, or some other defect has caused an electrical leak. 1) you need to separate the white neutral wire from the ground wire.

Check the wiring diagram on the back of the control. R in the case where the problem persists, it is important to have Have the system tapped off the protected side of a gfci outlet.

I have rechecked my connections to ensure they were correct. There are three ways this can be done. If the led still lights constantly, the gfci is defective and the thermostat must be eplaced.

Use a gfci protected circuit breaker. When doing so, does the gfci still trip? I was very careful to route the load and floor thermostat wires to the wall mounted thermostat unit.

The underfloor heating system will trip the rcd if a fault has been detected.
