Heated Floor Thermostat Gfci Keeps Tripping

The gfci trips if their is an imbalance between the two measurements. The system does not produce enough heat or takes too long to heat up.

Use a gfci protected circuit breaker.

Heated floor thermostat gfci keeps tripping. The underfloor heating system will trip the rcd if a fault has been detected. If the led still lights constantly, the gfci is defective and the thermostat must be eplaced. If the thermostat trips the gfci with no load attached, then the thermostat's gfci will need to be.

The thermostat is for flush mounts in a wall socket. The gfci will trip because loose connections, worn insulation, moisture, contact with human skin, or some other defect has caused an electrical leak. I installed a new fg thermostat and the thermostat gfci has been intermittently tripping the since it was installed.

The appliances plugged into the gfci, such as fridges and converters, can cause it to trip. Try turning the breaker off for a minute then back on, that usually fixes these gfi trip issues. Two or three months later (and almost simultaneously), two other thermostats began to trip.

Fifteen years ago, a contractor installed easy floor heating system under tiles in our lower level. If it does, other faults may be responsible, but if it does not, suspect circuit overload. Mat keeps heating floor after it should stop heating.

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. To see if it is circuit overload that is causing your gfci tripping, unplug the appliances plugged into the outlet. 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.

The test is successful if the red led on the right of the thermostat flashes once The control may have been bypassed. I have rechecked my connections to ensure they were correct.

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. Normally we'd be a little concerned that the gfi is tripping because something may be damaged under the floor. Other potential causes include faulty wiring, loose connections, and a faulty gfci.

Having both the thermostat gfi and bathroom gfi connected could be an issue. Use a thermostat with the gfci built into it. There are three ways this can be done.

Turn off the breaker, pull the thermostat, measure resistance between hot and ground and neutral and ground. 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. If you tried to reset gfci and keeps tripping, there maybe a fault in your floor heater.

When i turn the power on, the gfi built into the thermostat trips right away. Initially, resetting the unit would work for awhile, but later it would not set at all. Something you can check is to pull off the existing gfi face plate and remove the exiting gfi outlet (power off, and ppe) to.

If the gfci doesn't sense the same current on each wire than your leaking to ground somewhere. Try switching the thermostat off and then back on again. 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'.

208 v) 50/60 hz power supplies. 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. An electrician will need to test the system and ensure that it is not an issue with the rcd or electrical installation.

If you get near 0 ohms, you have a short. 1) you need to separate the white neutral wire from the ground wire. Set the thermostat to 'heat' the floor;

Reset the breaker and wait a few minutes to see if it will trip. The ground fault protection will guard against electrical hazards in case the electrical floor system is damaged. About five months ago, one of the thermostats began to trip flashing a gfi fault.

The system operates at 120 volts, but the thermostat is capable of using either 120 or 240 volts. When doing so, does the gfci still trip? I checked the resistance in the heating cable:

Here's a picture of the thermostat (complete with red light) There are four gfci programmable thermostats wired to 240v service. The imbalance when it trips is very small like 5 milliamps.

If thermostat is setup properly and activates the heating system as it's supposed to, underlying issue may often be with the flooring itself. It is important that the gfci is tested monthly. I was very careful to route the load and floor thermostat wires to the wall mounted thermostat unit.

Installation and use must be according to the national and local regulations. Have the system tapped off the protected side of a gfci outlet. Turn on the circuit breaker controlling the floor heating circuit.

R in the case where the problem persists, it is important to have
